Overview
A retrigger happens when you meet the trigger condition again inside a free spins bonus that has already started, adding more spins. It is also called a “re-trigger” or “extra free spins.” The spin count grows just as the bonus is about to end, so a single bonus lasts longer and has a higher expected payout.
The retrigger condition and the number of extra spins are set by each game. Some games let retriggers continue with no limit, while others allow only a few. The exact rules are listed on the in-game feature description screen.
How retriggers happen
| Method | Type | Highlights |
|---|---|---|
| Scatter re-landing | The set number of scatters lands again during the bonus | The most common type. Many games allow fewer scatters than the starting condition requires |
| Collection type | Collect specific symbols during the bonus to fill a gauge | Each time it fills, you get extra spins along with rewards such as a multiplier increase |
| Upgrade combo type | When specific symbols land during the bonus, a feature is upgraded and spins are added | Extra spins and a feature upgrade happen at the same time |

| Games | Retrigger rules | RTP | Max win |
|---|---|---|---|

| Sweet Bonanza Super Scatter | Starts with 4 or more scatters for 10 spins; 3 or more scatters during the bonus add 5 spins each time (no limit) | 96.51% | 50,000x |
| Book of Dead | 3 or more book symbols during the bonus trigger it again; the extra spins are added after the remaining spins | 94.25% | 5,000x |
| Big Bass Bonanza | Every 4 fisherman wilds collected add 10 spins, and the multiplier rises to 2x, 3x, and 10x | 96.71% | 2,100x |
| Wheel O` Gold | When 4 bonus symbols fill the gauge, the wheel adds a multiplier and 4 extra spins | 96.02% | 10,000x |

Even among retriggers, the character can differ quite a bit. With scatter-based retriggers like Gates of Olympus 2500, you never know when one will come, but there is no cap. With collection-based retriggers like Big Bass Bonanza, the stages are fixed, so you can see your progress on screen. In Big Bass Bonanza, the multiplier rises up to 10x at the third stage, so wins tend to cluster in the later part of the bonus.
Good to know
The retrigger chance is already built into the bonus. The RTP a game publishes already accounts for bonuses extended by retriggers, so a game that retriggers often does not have a higher expected value on its own. However, when retriggers chain together, the results of a single bonus can differ greatly, so these games are often designed with high volatility.
How often you enter the bonus (bonus frequency) and how often it retriggers are different numbers. Some games trigger the bonus often but it ends quickly, while others trigger it rarely but it runs long thanks to retriggers.
