Big bonus

Best welcome bonuses at online casinos

The welcome bonus is the offer a casino reserves for new players, usually a percentage of your first deposit up to a set cap, sometimes paired with free spins.

We highlight the casinos with the most generous welcome bonuses, without losing sight of the wagering requirements that determine an offer's true value.

How to read a welcome bonus

A "100% up to £500" bonus means the casino doubles your deposit up to £500. But the bonus amount must be wagered a certain number of times (the wager) before any withdrawal.

A big bonus with a high wager can be less rewarding than a modest bonus with a low wager.

The wager, the key factor

The wager (e.g. x35) tells you how many times you must stake the bonus. The lower it is, the easier the bonus is to turn into real money.

At KZYO, we display the bonus and its wager for every offer so you can compare at a glance.

FAQ

Is a bigger bonus always better?
No. A large bonus with strict wagering requirements can pay out less than a smaller but more flexible offer. Always check the wager.
Can you combine several bonuses?
Usually the welcome bonus applies only once. Regular promotions can then be added on top afterwards.
