How to read casino bonus terms

A bonus is defined by its terms, not its headline. Read six things: the match percentage and cap, the wagering requirement and what it applies to, game contribution, the maximum bet, the time limit and the maximum win. Together they decide what the offer requires from you and whether it is of any use at all.

A bonus headline gives one number. The terms give the rest, and the rest decides whether the offer fits the way you play. This guide lists the lines to read, with an invented offer to show how they combine.

An invented offer to read

Hypothetical offer: “100% match up to 200. Wagering 35× (deposit + bonus). Valid 7 days. Maximum bet 5 while the bonus is active. Slots count 100%, table games 10%. Maximum win 500.”

Other things to look for

Checks before deciding on an offer

  1. Work out the total wagering as a number.
  2. Divide it by the days available and by your usual stake.
  3. Check that the stake you plan to use is below the maximum bet.
  4. Decide in advance what you are prepared to lose, and whether not taking the bonus is the better option.

Frequently asked questions

Is a bigger bonus a better offer?

Not necessarily. A larger bonus with a higher wagering multiplier or a tighter time limit can be harder to clear than a smaller one.

Where do I find the terms?

In the promotion terms of the operator, usually linked from the offer. Read them before deciding on any offer. Declining is always possible.
