How 100% casino bonuses work

What is a 100 deposit bonus and how it works

There are many different bonuses and offers casinos give to their customers. It's good to know the basics of a 100% deposit bonus, also known as a 100% match bonus. The word ‘match' comes from the fact that the bonus percentage matches the deposit amount.

Out of the best 100 welcome bonus offers, approximately 60 per cent are 100% deposit bonuses.

Let's look at the following welcome offer: 100% match bonus up to £100. The percentage stands for the percentage amount you will gain as a bonus and the £100 stands for the maximum possible bonus amount.

In this case, you will get 100% more on top of your own deposit. If you deposit the maximum amount, you will have £200 in your account. Check the minimum deposit limit and make sure you deposit at least that amount.

If you deposit £50, another £50 will be added as bonus money to your account.

This means you will start with £100 in your account. Casinos usually separate these two balances. Therefore you will have your actual deposited balance and a bonus balance shown in your account. Every casino also has its own terms and conditions for 100% match bonuses. That's why it's always wise to read casino-specific terms before accepting bonuses.

It makes total sense why these kinds of bonuses are offered to newly registered players. This allows them to build their bankroll fast without breaking the bank. Players then get extended time at the casino to try out interesting games and discover what the casino has to offer. Bojoko has listed all the sites where you can get the best online casino bonus in the UK and you can explore other bonus types too.

Responsible gaming and casino bonuses

Bonuses are one way to attract players to the casino. They are an effective marketing tool for casinos in the ever-growing gambling industry. The competition is tough and new bonuses are invented all the time to keep the game on.

It is important to stay in control of your own gambling. Take advantage of the responsible gaming tools that the casinos offer, set your limits and stick to your budget. Don't ever use gambling as a way of making money and don't bet more than you can afford to lose.


A 100% deposit bonus is a bonus offer from the casino to its customers. You will get bonus money on top of your deposit and double your bankroll.

For example, if you deposit £50, you get an additional £50 as bonus money. Bonus terms and conditions vary in casinos, so make sure you read them through before accepting the bonus.
