Why the biggest bonus isn't always the best

A huge headline bonus can hide punishing terms. A $500 bonus at x40 wagering can cost more effort — and money — to clear than a $150 bonus at x20. What matters is the wagering requirement, whether it applies to the bonus only or deposit + bonus, and the time limit.

Before claiming any offer, run it through our bonus wagering calculator to see exactly how much you'd need to bet to withdraw it.

How to compare offers properly

Check three things on every bonus: the wagering multiplier, what it applies to, and game weighting (slots usually count 100%, table games far less). A modest bonus with fair terms beats a giant one you can never clear. Each review lists the full bonus terms.

Frequently asked questions

What is the best betting welcome bonus?

The biggest offers are ranked above by size, but the best value depends on the wagering requirement. Use our bonus calculator to compare the real cost of clearing each one before you decide.

What does a wagering requirement mean?

It's how many times you must bet a bonus before you can withdraw it. At x30 on a $100 bonus you must place $3,000 in bets. Lower is better.

Should I always take the biggest bonus?

No. A large bonus with high wagering or short time limits can be worse than a smaller, fairer one. Always weigh the headline figure against the terms.
