How We Review Casinos
When reviewing casino welcome bonuses, I focus on the overall value of the promotion rather than just the size of the bonus. A huge welcome offer might look attractive, but if it comes with high wagering requirements—like 50x, for example—low withdrawal limits, or tons of game restrictions, then there’s little point claiming it in the first place!
Once I’m happy that a bonus is generous and fair, I’ll move onto examining the casino itself. I look at everything from safety and security, to game selection, cashout speeds, payment method options, and even test out the customer support facilities!

What is a welcome bonus?
A welcome bonus is an offer that online casinos extend to new players when they sign up and/or make their first deposit. It may include free spins, bonus funds, or other incentives.
-
How can I claim a welcome bonus?
At most casinos, you’ll need to first register and make a deposit. Some casinos may require a separate bonus code or that you contact customer support. Always be sure to read the terms and conditions of the bonus.
-
Can I withdraw the welcome bonus immediately?
Usually, you cannot withdraw the bonus money right away. You must first meet the wagering requirements set by the casino. Once these requirements are met, the bonus money becomes real money that you can withdraw.
-
Why do some casinos not offer a welcome bonus?
Some casinos might focus on other benefits like cashback offers, weekly promotions, or VIP programs. Or they might want to stand out from the crowd by providing a different gaming experience without traditional bonuses.
