Irregular play in bonus terms
Irregular play is the label an operator puts on betting that it says breaks the conditions of a bonus, and it is usually the stated reason for voiding the bonus and any winnings built on it. It is a contract term, not an accusation of crime. You meet it at the withdrawal stage, when a payout is held and the terms are quoted back at you. Practice varies between operators: some list every banned pattern, while others rely on a vague catch-all that leaves them the final word.
What the irregular play clause covers
There is no single industry definition, so the meaning is whatever the operator’s own terms say. In practice the clause gathers up a handful of familiar breaches that sit alongside the wagering requirement.
The common triggers are a stake above the maximum bet while bonus funds are active, play on games the promotion excludes, and low-risk patterns such as covering both red and black on roulette to clear turnover with almost no variance. Opening a second account to claim a welcome offer twice also lands here, although many operators treat that under separate fraud rules.
The money at stake is easy to work out. A 40x wagering requirement on a €100 bonus means €4,000 of bets, and a single spin over a €5 cap on bet 3,900 can be enough, under some wording, to void the lot.
The phrase to look for
Watch for the words “including but not limited to” after a list of examples. They mean the list is not complete, so the operator keeps room to call other behaviour irregular after the event. That is the weakest position you can be in, because you cannot know in advance whether a given bet is allowed.
Read the specific promotion’s terms, not only the general ones.
Irregular play versus fraud and cheating
The two clauses are often printed side by side and confused with each other. Here is how a well-drafted irregular play term usually compares with a fraud or cheating term, judged by which one gives you the clearer footing.
Irregular play clause | Fraud or cheating clause |
|---|---|
| Targets breaches of a promotion's own rules, such as maximum bet or excluded games | Targets deliberate cheating: collusion, software manipulation, stolen or third-party funding |
| Wording often vague and open-ended, leaving discretion with the operator | Usually describes concrete acts that leave a record |
| Sanction normally limited to the bonus and winnings from it | Can mean closure of every linked account |
| Disputes turn on how the operator reads your betting pattern | Disputes turn on evidence of a specific act |
How regulators have treated the term
The clearest public guidance comes from Britain, not Ireland. The Competition and Markets Authority’s investigation into online gambling promotions found that rules restricting certain play strategies were potentially unfair, and that firms relied on them to deny payouts when customers came to claim winnings.
Following that work, the UK Gambling Commission told licensees that every prohibited type or pattern of play must be listed specifically, that a general reference to banned play is too vague, and that operators must not reserve sole discretion to decide when play breaches the terms. It also asked that fraud and cheating terms be kept separate from promotional play restrictions, which is why the comparison above matters.
That guidance binds operators licensed in Britain only. We did not find an Irish rule addressing irregular play clauses by name, so treat the British standard as a useful yardstick rather than a right you can enforce here.
Irish bonus rules are evolving under the Gambling Regulation Act 2024.
What to do when it is applied
Ask the operator, in writing, which clause you are said to have broken and which bet broke it. A fair decision can point to a rule that was in the terms when you opted in and to the transaction that crossed it.
Check whether the sanction touches your own deposit or only the bonus and its winnings. Typical wording covers the bonus side; if your deposit is being withheld as well, say so plainly in your complaint and quote the clause word for word.
If the operator’s complaints process does not settle it, you can escalate through whatever dispute route its licence provides.
If the dispute is about more than money and play has stopped feeling like your choice, set a deposit limit or self-exclude with the operator, and ring the Gambling Care helpline or contact your GP for support.
