Bonus buy slots

What qualifies and how it is ordered

A slot is included when our data marks a bonus-buy feature. The order follows the RTP published by the provider. Some games list a different RTP for the bought round than for normal play, so open the game info to see which applies. Ordering by RTP is a convenience for comparison, not a ranking of quality.

The bonus buy guide explains the cost multiples and how buying changes variance.

Not available everywhere

Some countries and regulators ban or restrict bonus buys. A casino may switch the feature off for players in those places, so a slot on this list may not show the buy button for you. Respect those local rules. Operators may void play that breaks their terms, and a regulator's ban exists for player protection reasons. If the button is missing, that is the intended outcome, and the slot can still be played in its normal mode.

What to check

A buy often costs many times your normal bet, so a single purchase can use a large share of your balance. The result of the bought round is still random, and it may pay less than it cost. Spending faster means losing faster.

Check the volatility in the slot's review and our slot volatility guide, then decide on a limit before you start. Our responsible gambling page lists tools that help.
