How to Read Casino Bonus Terms and Conditions

By Big Spins Bonus Editorial TeamPublished 28 April 2026Updated 30 July 20265 min read

The headline figure on a casino bonus — '£50 bonus' or '100 free spins' — is only ever part of the story. The terms and conditions attached to it determine how easy or difficult it actually is to benefit from the offer, which is why they're worth reading before you deposit, not after.

Start with the wagering requirement and which games count towards it. Then check the minimum deposit needed to qualify, any maximum bonus conversion cap (a limit on how much of your winnings you can actually withdraw), and the expiry window in which the bonus and any winnings must be used.

Free spins often carry their own separate conditions: a per-spin value cap, a restriction to specific games, and their own wagering requirement on any winnings generated. It's common for free spin winnings to be paid as bonus funds rather than cash, which brings its own wagering requirement.

Finally, check eligibility conditions — some offers are restricted by region, payment method, or device — and whether the promotion is a one-time new-customer offer or something you can claim repeatedly. If any of this isn't clearly stated, treat that as a warning sign rather than assuming the best case.
