What is a retrigger in free spins?
Last updated:
A retrigger happens when scatter symbols land again during a free spins bonus round, awarding additional free spins on top of those still remaining. It extends your bonus round and can significantly increase the total number of spins you play.
How retriggering works
If a slot awards 10 free spins for 3 scatters and you land 3 more scatters during those spins, you might receive another 10 free spins (or the same amount as originally triggered). Some games cap the maximum number of free spins through retriggering while others allow unlimited retriggers.
Why retriggering matters
A single retrigger during a good multiplier phase can dramatically increase the value of a bonus round. High-variance slots often owe their most spectacular results to multiple retriggering combined with escalating multipliers. The probability of retriggering is built into the slot’s math and affects the game’s overall variance and potential max win.

After building up a solid grounding in casino, sports betting and poker, he made the move to Malta where he spent close to a decade writing for some of the biggest affiliate networks in the region. A few years ago he relocated to Bali, which shifted his focus toward website strategy and affiliate marketing. The casino side never really left, though. He still writes reviews, how-to guides and in-depth pieces on everything from slots and live dealer tables to crypto casinos and sweepstakes sites. His approach is fact-first: help players understand how online gambling actually works before they deposit a cent.
