This page will give you all the information and get you started, explain basic and expert stuff followed by some amazing casino tips.

Selecting your bonus

Whenever it comes to sign up in a new online casino it is important to consider the overall feeling you get, however you should as well have a look how much you are going to get for your first deposit. Even though speed, usability and licensing are tremendously valued now a days and they should not be underestimated the bonuses on offer and what it is that you are looking for in an online casino. Do you love to play table games? If so then a casino focused purely on providing free spins is probably not a good fit. Are you a high roller? Then you need to find a casino with an appetite for big high roller bonuses and high limits.

The bonuses will also give you a chance to feel and understand if the casino is just another white-label that is mainly run by templates and straightforward CS effort or there is actually genuine gaming expertise. Are the bonuses being credited in real time to make your experience smooth and easy? Are the support teams knowledgeable and helpful when you question a promo? These are questions which are important to the longevity of your relationship with a casino.

Here are all types of bonuses available as we would explain them to new or existing player at an online casino brand.

Casino Bonuses are one of the things of online casinos when you’re looking to play without depositing your own funds, or simply to extend your gameplay and increase your stakes. This section explains the most common types of bonuses offered by online casinos. At we have categorized the best casino bonuses for you, available to grab straight away!

NOTE: Casino Bonuses always come with wagering requirements and certain restrictions. Before opting for a bonus, always make sure you fully understand the bonus terms and conditions which should be available for you to read at all online gambling sites. If some of the points are unclear you should always seek and advice from the Customer Support at the respective site.

What types of bonuses are available in most of the online casinos?

Deposit bonuses are the most widely offered types of bonuses by online gaming brands. The deposit bonus is a percentage of your deposit amount that is in most cases added in your gaming balance on top of your deposit amount. These types of bonuses always come with wagering requirements which players are required to meet before making a withdrawal and cashing our their winnings.

For example, a 100% deposit bonus up to 100 EUR with wagering requirements of 20 times the bonus amount means that you will receive 100 EUR bonus money on your deposit of 100 EUR or more and you will need to wager 2000 EUR ($100×20=$2000), in order to withdraw your winnings.

Different kind of deposit bonuses


Cash Bonus: a percentage bonus with wagering requirements on the bonus amount and deposit*. Cashable means that you’re allowed to withdraw the bonus amount after completing the wagering requirements.

Sticky Bonus: a percentage match bonus with wagering requirements on the bonus amount and deposit*. As the name implies, Non-cash means that you’re not allowed to withdraw the bonus amount and that it will be deducted when you complete the wagering requirements from your balance.

Gem Note: Depending on the casino the technology powering the brand, the representation of the cash balance and the bonus balance can vary. Back in the days when most of the casinos were powered by technology dinosaurs such as Playtech, Microgaming, Gtech, there was no separation between the real money balance and the bonus balance. When depositing 100 EUR you get 100 EUR more, and the Main Balance gets 200 EUR. Until you play through the wagering requirement you are not allowed to request a withdrawal.

In modern casinos, there is a clear separation between the real money balance and the bonus balance. Brands nowadays allow the player to freely play first with his real money balance and gamble at his own pace and stakes and afterwards they are imposing restrictions and wagering requirement on the bonus money.

Welcome Package Bonus: a range of different bonuses with wagering requirements on the bonus amount and deposit*. These types of deposit package bonuses consist of more than one deposit match bonus and are often combined with free spins, bonus and cash bonuses.

Premium Bonus: we are making sure we bring you the best possible selection of Premium Casino Bonuses available at online casinos today. Premium bonus means that these range of bonus offers are not available at any other casino, not because they are huge amount, but because of the definition of the bonus. Our premium promotions can be found nowhere else!

Insurance Bonus: as the name implies, this is real cash back given from online casinos to depositing players with or without wagering requirements. Insurance or cashback bonuses are available as part of the retention efforts of VIP managers at the casinos.

High Roller Bonus: a unique variety of bonuses available for VIP players. These high roller bonuses may vary from a percentage of your deposit to exclusive free gifts, cashback, rebates and many more.

Free Spins Bonus: an amount of free spins added to a slot game. Free Casino Spins are most often offered as a free casino gift (no deposit bonus) and are part of online casino promotions. These types of bonuses almost always come with wagering requirements or max amount you can get out of them, but some online casinos strictly have no wagering on free spins.

Bonus money: bonus money bonus that comes with special terms and conditions. Bonus money offers are designed to get you familiar with the games before playing for real money. By using such bonuses players can score bigger cash bonuses by depositing the minimum amount at an online casino.

Gem note: As tackled a bit earlier, the bonus money offer is one of the most popular instruments to incentivize players. It is extremely important to pay attention to the terms and conditions, where it says how exactly are organised the bonus wagering requirements. In some of the cases you start playing through the wagering requirments in the moment you receive the bonus, even rolling the bonus over with real money. In other cases you need to first play out you real money and then you are going to be able to start playing with the bonus and rolling it over.


 Bonus money and Free Spins on registration are some of the frequent offers casino brands are employing to attract players. These types of No Deposit Bonuses almost always have wagering requirements and a maximum limit on the amount you can turn into real money and withdraw.

A standard procedure is for online casinos to impose these limits in order to mitigate the risks involved with bonus abusers and unscrupulous players. The maximum amount you can withdraw by using Free Cash or Free Spins bonuses may vary from $20 to $5000, depending on whether you are a new or existing player.


Free Bonus Money: free bonus money wagering requirements and most often a maximum amount to credit after the wager. Free Bonus Money is the most popular online casino No Deposit Bonus and players can win real cash without the need to deposit.

Free Spins Bonus: an amount of free spins added to a particular slot game. Free Spins are played up to their amount and the cumulative win is then available for you to play with and it’s normally a bonus money that comes with wagering requirements.


As lovers of casino gamble around the globe have discovered there is no better place to play than at recommended online casinos. Land based counterparts may offer the odd free drink or dinner but our online casinos offer the most amazing Welcome Bonus packages imaginable.

As genuine followers of the caisno game it is fair to say that even tough land based casinos may offer great ambience, food and pretty looking courpiers, the online casinos offer the most amazing and biggest welcome bonus deposit packages.

When it comes to bringing that mind blowing jackpot down you need to be turning over those reels or placing stakes on your lucky tables. Deposit welcome bonuses packages give you free bonus money to bet with, increasing the chance of becoming a celebrated jackpot winner!

The most of the promotions currently available at online casino brands can be quite generous and that is the first reason why players are fond of them. Although in some of the casinos the cost of bonuses is deducted from the profits, in the casinos we are collaborating with you get the full bonus amount even after you have played though the wagering requirements.

So, why not take the chance and grab that deposit bonuses and beat the casinos more often, ?

Be sure to get the maximum value from your Welcome Bonuses by taking up the maximum number of deposit bonuses. Rather than just using the free spins if the casino offers 200% on your first 5 deposits we recommend making all 3 or 4 deposits to ensure you get all the bonuses the casino has to offer. Then play those bonus money on progressive slots and see if you are their next millionaire!

Gem note: Make sure you read the terms and conditions of the casinos where you have decided to deposit. In most of the casinos we are collaborating with first you get the chance to play with your own money at the games you want and with the maximum bet you wish. Look for the most generous slots in terms of RTP ratio in order to make the most of your own money. Only once you start playing with your bonus money, this is the moment when certain restrictions with regards to games, max bet per spin and other may apply.


Most of the casinos around offer some sort of incentives in order to attract players and show their appreciation for choosing to them over their competitors. The most common of them all are deposit bonus. This mainly means that when a new player deposits money for the first time regardless of the way of funding, they will get much more on top than what they have expected. Anyways, this page lists a number of casinos that are offering more a package bonus that goes beyond the standard deposit bonus including free spins, top up on winning in the first spins and many more. Some online casinos combine deposit bonuses with a number of free spins, no deposit free spins.


Deposit bonuses are pretty straight to the point as the name suggests. Most online casinos offer these kind of deposit bonuses where players deposits are matched or player get more bargain than expected with bonus money up to a certain amount. For example, if a casino brand offers a 100% matched deposit up to 300 EUR, it simply means that the casino will match up the deposited amount in bonus money and have double the amount plus the you have deposited. Moreover, if a deposit of €100 was made, the player will have a total of 300 EUR to play with. As usual, the bonus money cannot be withdrawn straight away, but will need to be played through a number of times before it’s possible to withdraw the bonus funds. This is why it’s important to read through the terms and conditions as trying to withdraw the bonus funds before the wagering requirements are met might forfeit the entire bonus funds.

Retention Bonuses

Reload Bonus

Once the time of your first couple of play is long gone and you are more familiar with the casino brand, you have deposited and withdrawn several times and it seems that you have started to like the products and the services of certain casino, most of the casinos will start offering you the so called reload bonuses. They pretty much the same as the deposit bonuses. They can come in different form, such as 20% up to 100 EUR from the deposit. It could be 10% top up on all of the deposits this week or on the next 5 deposits, or on every 3rd deposit. The variations are limitless as long as the platform provider of the casino is capable of sustaining and offering them. Fortunately, all of the casinos we are collaborating with are well researched and you can be sure that that the more you play the more usual reload bonuses will be coming your way. The bonus money that will be received from these reload bonuses will be again related with some play though requirements before they can be turned into real money.

Insurance bonus

For most of the casino players that have been around and played in some of popular casinos, you all should be familiar with the so called cash back or the insurance bonus as we like to call it. For the ones that aren’t familiar with the structure and the meaning of the insurance bonus, it is fair to say that you first should have had been unlucky during some period of time. The operator might make to following very popular offer: This weekend we have got your back covered, play on any of our live dealer games and if you happen to be unlucky we will give you back 20% of your eventual loses.

Gem note: When it comes to cashbacks or insurance bonuses it is very important to go through the terms and conditions of the offer in order to make the most out of it. When the casino brand talks about 20 % of the eventual loss, make sure if they refer to the net loss(bets-winnings) and if this formula includes the bonus money or excludes it. It is very very probable that the technology that the online casino is using is incapable of making the separation. Yeahh, even some of the biggies have this problem in the moment, as the growing number of the customers is in a disproportion of the capabilities of their platform provider. Even more, thanks to more websites such as CasinoBonuses.Review, the players are maturing faster than the operators can cope with.

Free Spins

As previously mentioned in this section related to bonuses, the free spins can be used as that well for acquisition of players as well as for retention purposes and they are part of the promotional arsenal of the casinos. It is very important to make a clear separation between the free spins that player receive from the slot game itself and the free spins that casino brands grant to players as promotional initiative. In the case where free spins came from the slot itself, the player can clearly see that upon scoring a certain combination of scatters of symbols they unlock free spins. In other cases the collection of certain symbols will bring the free spins. In some casinos, the Free Spins are called Bonus spins in order to avoid the confusion with the free spins coming whiting the game.

Gem note: And we hope as many players as possible experience the thrill of getting free spins, and in the free spins you get several rounds of additional free spins. Well, guys, I believe that this is the cherry on top of the cherry of the Sunday awesomeness called: “gimme that juicy payout”..:)

Bonus Spins

Essentially the Bonus Spins are Free Spins as mainly referenced and promoted in all online casino brands. In some online casinos, in order to avoid confusion,  bonus spins term is introduced to differ them from the free spins coming from the slots themselves.

Free rounds

The free rounds is a variation of the bonus and free spins, ideally they come on a specific provider such as QuickSpin or Ygdrassil. Some of the well progressing casino game studios, have the possibility to offer players Bonus/Free spins to player. The particularity is that the player can choose the stakes of these spins and experience the slot game before making up his mind to deposit and chase the big win.

Feature Trigger

This is what a promotional tool that casino brands are using when they want to be generous. In some games from providers like Quickspin, you can be eligible for Free/Bonus Spins upon an action you are asked to undertake, then the spins come surprisingly after your next natural spin.

Rebate Bonus – You play, casinos pay.

Rebate bonus is a rare form of incentivizing the players. It is very typical for players which are spinning frequently and are making huge volumes of bets with any kind of stakes. In is very often seen in Asian facing casino brands that they offer certain percentage on top of the amount of the best you make. It is in the range of 1-2 % it really depends on your style of  gameplay, frequency and stakes. It is considered as generous incentive as it awards directly your bets, regardless of the results. Bundle up, lock it up this is going to be a doozy one..:)

Top up winnings

Make ten bets with bet amount 10 EUR and we are going to give you 100 % on top of the winnings of these particular bets. This is a form of promotion that you rarely will see around. And the reason behind that is very simple.

Gem note: The limitation around bonusing and interesting ways of incentivizing the player lies down what kind of platform the casino brands have based their operations. I am sure you have asked yourselves why all you see around is deposit bonus oriented offers and fee spins. The answer is simple: In order to bonus let’s say large amount of players in real time operators need to have the proper infrastructure and instruments. Long gone are the days when tens of people are manually crediting bonuses on the next day of the promo.

We are collaboration with casino brand, where casino bonuses are credited in real-time and tend to be fair and transparent when it comes to wagering requirements

Daily missions

With the introduction of gamification, some of the casino brands introduced the so called daily missions. Players are presented with three daily mission to spin hundred times in certain game, to win 5 times in certain game or to play certain amount of time. All these tasks are awarded either with free spins in similar game or with bonus money.


Tournaments come in different forms depending on the casino brand. In most of the casinos tournaments are mainly driven and delivered via certain game studio such as Quickspin, Playson, Pragmatic or any other. The reason for that is that, again, most of the online casinos out there are run on platforms that lack the marketing capacity to organize a tournament with mixed portfolio of games. A form of tournament could be win 20 times in certain game and this action will give you 1o points, or for every 10 EUR bets you get 1 point. Accumulated point will push you up in the scoreboard. The winners usually get a share from the prize pool.

For game providers such as  they offer  tournaments in collaboration with Competition Labs. A thrilling  combination of  game events allows for more interesting tournaments where the goal for the players are ‘event’ oriented, in addition to win/turn over oriented. Every Quickspin game has 6 unique game events we identify and communicate over our API to operators. Any of these game events can function as measurement for a player’s success in a tournament.


Challenges are type of promotional activities mainly driven by certain casino studios. Premium online casinos which offer Quickspin can lure players into a world of challenges and interesting characters.

Quickspin Challenges are a seasonal themed retention tool designed to offer some extra excitement on our slots.

It is a mini-game that is being displayed on top of our slot games, and the gameplay of this is fuelled by the outcome of spins from the slots game. Players need to get a character through the maze to a prize. The character moves towards the prize automatically when a pathway is generated

Achievements races

Another promotional feature that casino game studio Quickspin offers is achievement races

Achievement Races help to put the spotlight on our Achievements module. For a set period, the operator can choose to have the progress towards all achievements on the chosen game(s) to be hastened by 200, 300 or 400%.

Whenever any of the events relevant to the achievements occur, the player will receive +2, +3 or +4 (instead of the normal +1) as their progression.

Lottery tickets

Online casinos organize a lotteries among their players in order to stimulate more turnover or ask the players to collect wins or make deposits. In exchange for that, players receive lottery tickets. The more you play, the more tickets for the lottery you receive, the greater the chance to win.

Think before you ink

Bonuses bring a bold promise for all new players. We would like to remind you, that casinos are in the business of making cash for their owners. Some of the best bonuses out there are tailored to appeal to a broad audience rather than reward gambling skill and foresight. All in all, though,what we are trying to achieve here is to bring to you offers that you can find anywhere else but on CasinoBonuses.Review. And if you are more of the recreational player sort, then there is no shame in that either, we have got you covered! Always budget your game play, if you are on the losing strike, take a break and try another day. Play responsibly and if aint fun any more just.


Banking at online casinos is one of the key factors in a successful online gambling business. Online casino brands tend to be offering a wide range of payment options in their cashier where players can recognize their local payment option and or explore new ways of funding their accounts. In most of the cases you should be aware that depending of your geographical location there might be certain restrictions in terms of the payments methods which are listed in the cashier. Make sure you are browsing the net with your VPN switched on. Even though local payment options are among the most preferred ways of uploading money, we believe that Debit or Credit cards remain the most frequent way of depositing in an online casino.

Another method for depositing that has gained significant traction in the online gaming industry is the digital wallet. Interesting story that many of the player don’t really know is the origin of the digital wallet Skrill(formerly known as Moneybookers). The idea and the technological solution goes long back in the offices of one of the first online bookmakers Gamebookers. The developers and the management were looking into the idea of launching a method which one side protects the data of the user and acts as a mediator between the bank and the online bookmaker, and other side lets the user use his email as unique identification when creating an account and sending money around.

They beta- launched the digital wallet as part of their portfolio of payments and in short period of several months, the payment method became a popular way of funding the newly registered accounts. The management of the company sooner found out that can extend the service and let the players transfer money between account using their email, and the payment method became quite popular way of exchanging funds among the players first on their own brand Gamebookers and then the company took up on its own path becoming now one of the most important digital wallet globally.

Skrill, Neteller, Ecopayz, Paypal are all digital wallet that the modern casino player knows, trusts and uses some of them in his day to day interactions with friends, family or other online retail business. Even though most of the players come on the online casino brands websites already and they have already decided what will be the way of funding the account. It is sometimes worth looking into the promotions section, as casino brands tend to offer generous offers related to a specific payment method.

Gem note: The reason for the promotions that are related to a specific payment methods is very simple: With the increased pressure of local regulations, online casino brands are exploring the payment landscape and searching for a new payment options that can be flexible and trustworthy enough to be offered to the players. Players should not be afraid to try out new payment methods.

In most cases casino brands have gone through the lengthy way of due diligence with the payment provider and you can be assured that your money is safe with the payment method.

Prepaid cards

These can usually be bought at any kiosk or online and there are three types: virtual cards, reloadable and disposable.

Below there are several prepaid options to check out for depositing, each one may be dedicated to a certain country so make sure to double check which countries the method supports.

  • -Paysafecard
  • – Entropay
  • – Neosurf

Bank wires

Back in the days when one of the few options to deposit online was credit or debit card. The bank transfers were as well that some players were using. The problem with the bank transfers is that usually they are treated as international wires between the bank account of the player and the gaming site. The transfer to be reflected as settled is a lengthy procedure and depending on the banks it can take up t 3’5 working days.

Online banking

As technology is evolving the banking services improved and companies that were observing the online gaming world and its need and dynamics certainly knew there was a room for innovation. Companies such as Trustly Klarna and Skrill already pretty well involved in the online gaming introduced online banking services letting the layer deposit instantly with their online banking and have their online casino balance topped up in real time with no delay at all.

Gem note: For players that are used to shop with their online bank account, you should look around in the cashier for Rapid Transfer. An online banking services offered by Skrill, which lets you deposit with your bank account regardless of the bank. Usually most of the banks are covered.

Crypto currencies

In an attempt to completely decentralize the economic order, and the way people look at the value of currencies, developers introduced a whole new format – cryptocurrencies. Bitcoin was the first crypto asset introduced, with many additional digital currencies being built on its basis. Nowadays, there are a few which have managed to gain the most ground in the field of online banking.

Bitcoin – This was the first currency of its kind, developed as a decentralized and completely anonymous method of sharing and transferring data and funds between peers. It runs on its unique blockchain platform, which later served to develop all kinds of ‘derivates’, operating today as separate crypto currencies.

Ethereum – So far, Ethereum has managed to establish itself as the second largest cryptocurrency after Bitcoin. It inevitably uses its revolutionary technology, and further builds upon it in order to perform its operations successfully.

Bitcoin Cash, Dogecoin, Litecoin

Online Slot Dissection

Classic slot machines have three reels with only one horizontal payline. Today’s video slots usually have five reels, multiple paylines, special game features and bonus games which gives the player more winning possibilities. These are the common basic parts of a slot machine.

Symbols are nice images that often spin vertically. A symbol’s value fluctuates, and usually the rarer it is, the higher the value it pays out.

Reels are vertically spinning groups of symbols. When they stop, random symbols come out. Slot machines usually have 5 reels

Coin value and Bet Level both adjust how much you gamble per spin. Decreasing or increasing the dials will lower or higher your bet amount

Paylines are paths going across the reels, usually from left to right. Alignment of identical symbols on one or more paylines means win.

Spin is the button you click to start the game and get the reels rolling. Similarly, Autospin spins continuously for a specified time.

Paytable is a list of payouts on a slot machine. This shows how many coins or credits the player will win for each combination of symbols.

How to win`playing Online Slots

Depending on how the symbols fall when the reels stop, you may get a winning combination. Usually you win by collecting three or more identical symbols in a row from left to right. The more pay lines a slot has, the greater chance of winning, and the more complete a pay line is, the more you win. How you win, and how much you win, is also affected by the various game features and feature symbols that most games have. Check the games’ pay table for detailed information on how to win.

Tumbling reels

These are also known as Avalanche feature / Cascading reels / Dropping symbols. As line wins are awarded, the winning symbols disappear, causing symbols from higher up on the reels to fall down into their place. This creates brand new possibilities to win big without risking any additional credits.

Slot with Tumbling reels: Gonzo’s Quest


Multiplier is a feature that often is combined with tumbling reels. The multiplier simply multiplies your respin win. How many times depends on how many wins you win in a row.

Free Spins

Free Spins are usually triggered by the combination of so called “Scatter symbols”, but sometimes in other ways. During these rounds, some more perks can be given, which usually means bigger wins than during the classic gameplay.

Expert stuff

Once you’re familiar with the basics of slot machines, it’s time to take it to the next level. Here are some more advanced slot terms you should learn in order to become a full fledged casino pro.

Hit frequency

Hit frequency is defined as how often a slot machine will have a winning outcome. A hit frequency of 10% means that 1 out of 10 spins has a winning combination. Machines with lower hit frequencies tend to offer larger wins when it pays.

Payback rate (RTP)

Payback is an overall percentage that a slot gives back to all its players. This percentage is usually around 90-99%, depending on the slot.


This basically measures the size of the winnings. Low volatility slots will give you lots of little payouts often, whereas slot machines with high volatility work the other way around.
