All you need to know about bonuses

Online casinos are really good at acquisition. They offer a whole range of welcome bonuses to their new players. These bonuses are a determining criteria for some players when they decide where to play. In this guide, Become Gambler will explain to you every type of bonus you can encounter when playing on an online casino.

The welcome bonuses

You will encounter two categories of bonuses when playing on an online casino: welcome bonuses and regular promotions. In the first part of this guide, we will talk about the different kinds of welcome bonuses that exist. Just remember one thing: you are not obliged to take a welcome bonus. Only activate it if you want to play with it, as it comes with conditions.

Welcome deposit bonuses

The first and most common bonus that is offered by online casinos are deposit bonuses. You deposit a certain amount of money, and the casino matches your deposit to a certain percentage. Let’s say you are facing a casino with a 100% up to 500€ welcome bonus. It means that you can get up to 500€ bonus money. As the percentage here is 100%, if you deposit 500€, you will get 500€ of additional bonus money added to your balance.

It’s a great kind of bonus, especially for players who does not want or can’t deposit a big amount of money on an online casino. It allows them to discover the casino with a boosted balance, and to place bigger bets than they usually would with a small balance.

Become Gambler casino partners offer a lot of welcome deposit bonuses. Don’t hesitate to discover them by visiting our Online casino bonuses page.

Free spins at registration

Another kind of welcome bonus is free spins that are offered to players. Some casinos offer these free spins at registration, without having to deposit. Others are offering them on top of a deposit bonus, as an additional gift. Before accepting free spins, always check the casino’s bonus terms and conditions. Free spins and deposit bonuses usually have different wagering requirements.

Free money at registration

After free spins comes another kind of bonus which is free money offered at registration. Yes, you read this right. Of course, as nothing never comes really free this bonus comes with conditions. The main one being that most of the time you can’t withdraw more than 100€ from the winnings you make with this offered money.

The regular promotions

Welcome bonuses are great, but once you have taken advantage of most of them, what’s left? Lucky for you, casinos thought of everything and offer really good regular promotions as part of their loyalty programs. This is what these promotions are for: keeping players engaged. From one casino to another, these promotions can be very different. Let’s learn more about these.

Deposit bonuses and free spins

Deposit bonuses are not only for new players, but also for players that are already actively playing on a casino. As they are offered on a weekly basis, their amount is less important that the welcome ones.

Most casinos also offer free spins on a regular basis. To claim these free spins, you usually have to make a small deposit (20€ or 30€ in general).

Contests and challenges

As a way to motivate and engage their players even more, some casinos host contests and challenges. During these special events, hosted either by the casino or a game provider, players are competing against each other. In general, players are competing to achieve the best multiplier on a selection of slot machines.

Cashback and rakeback

Last but not least comes two very interesting perks some casinos offer to their players: cashback and rakeback. Let’s see what these two consist in.

Cashback and rakeback are essentially the same. The casinos that have this feature enabled give you back a percentage of the house edge. The more you play and progress through the loyalty levels, the higher this percentage can get.

Most casinos are giving players their cashback on a weekly or monthly basis. More and more casinos are offering “instant cashback / instant rakeback”. This means that you can collect it at any time during your session, by going to your cashback balance.
