Bonus abuse: what casinos mean by it and how to stay within the rules

By The Casino Deals team · Updated 8 November 2026 · 5 min read

Bonus abuse is the term casinos use when they believe someone has broken the rules of a bonus to gain an unfair advantage. Most players never go near it on purpose, but a few common mistakes can still lead to winnings being removed. Here is what bonus abuse usually covers, the rules that trip people up, what a casino can and cannot do, and what to do if you think a decision is wrong. 18+.

What casinos mean by bonus abuse

Casino bonus terms usually include a section on bonus abuse or irregular play. It describes behaviour the casino will not accept while a bonus is active, such as playing in a way designed to clear wagering with almost no risk, or claiming a new-customer offer more than once. If the casino decides the rules were broken, it can remove the bonus and any winnings made with it.

Common rules people break by accident

Going over the maximum bet. Most bonuses cap the stake per spin or hand while you are wagering. Casino Compare explains max bet rules in detail.
Playing excluded games. Some games are banned or count for nothing while a bonus is active.
Low-risk betting patterns. For example covering both red and black on roulette to wager with little risk.
More than one account. Welcome offers are normally limited to one per person, household or device.
Using an excluded deposit method. See payment method exclusions.

What can happen if a casino decides it is bonus abuse

The usual outcome is that the bonus and winnings made from it are removed, while your own deposited money is returned. Repeated or deliberate breaches can lead to the account being closed. A casino should be able to point to the specific term it is relying on. Vague wording that lets a casino keep winnings for any reason it likes is the kind of term consumer law and the Competition and Markets Authority have warned against.

How to stay within the rules

Read the bonus terms before you opt in, especially the max bet, game and payment rules.
Keep your stake size steady while wagering.
Stick to one account per person.
If you are unsure about a game or bet, ask support in writing before you play.
If you would rather avoid the rules, play without a bonus or forfeit it before you start.

What to do if you disagree

Ask the casino to tell you, in writing, which term it says you broke and how. If you still disagree, use its formal complaints process. Casinos licensed in Great Britain must offer an independent alternative dispute resolution (ADR) service, so if the complaint is not resolved you can take it there free of charge. Keep screenshots of the offer terms and your game history.

Bonus abuse FAQs

Is bonus abuse illegal?

Not usually. It is a breach of the casino’s terms rather than a crime, but deliberate fraud, such as using someone else’s identity, is a different matter.

Will I lose my deposit if a casino says I abused a bonus?

Normally the bonus and bonus winnings are removed and your own deposited money is returned. Check the terms of the specific offer.

Can a casino close my account for bonus abuse?

Yes, it can close an account for serious or repeated breaches of its terms, but it should explain the decision and follow its complaints process.

Does playing without a bonus avoid these rules?

Yes. Bonus abuse rules only apply while a bonus is active, so declining the offer means only the standard account terms apply.
