The max bet rule

A no max win bonus can still be lost on one spin. The max bet rule is the term that voids more bonus winnings than any other, and it's the easiest to break by accident.

What it is

While a bonus is active, the casino limits the size of each bet. The limit stops players from clearing wagering in a handful of huge spins. Break it once and the casino can confiscate the bonus balance and its winnings.

How it is written

FormExample
Fixed amount"Max bet £5 per spin while bonus funds are active"
Percentage of bonus"Max bet 10% of the bonus or £5, whichever is lower"
Per round across games"Max £2 per hand on table games"

The UK stake limit sits on top

UK slots have a legal limit of £5 per spin (£2 if you are 18 to 24). The bonus max bet can be lower than this, never higher in practice. Whichever is lower applies to you.

Five ways people break it without meaning to

  1. Leaving a stake from earlier play. Slots remember your last bet. Check it every time you open a game during bonus play.
  2. Gamble features. Doubling up a win can count as a bet above the limit.
  3. Switching to table games. Different games can have different max bets.
  4. Deposit and bonus in one balance. At many casinos the rule applies until wagering is complete, even while you are playing with your own money first.
  5. Forgetting after a big win. A large balance tempts bigger stakes. The rule still applies until the bonus is cleared.

Simple habit: before your first spin with a bonus, write the max bet down. If you want to play bigger, forfeit the bonus first: you keep your deposit and its winnings, and nothing can be voided.

Frequently asked questions

What is the max bet rule?
The highest stake you may place per spin or per round while a bonus is active. It is usually a fixed amount (often £2 to £5) or a percentage of the bonus.
What happens if I break the max bet rule?
The casino can remove the bonus and everything won with it, even if the oversized bet lost. It is the most common reason bonus winnings are voided.
Does the max bet rule apply to no wagering offers?
Usually not, because there is no bonus balance being played: winnings are already cash. Check each offer's terms.
Do bonus features count as a bet?
Gamble or double-up features count as a separate bet at many casinos and can break the rule. Bonus buys do not exist on UK sites.
