What is a retrigger in free spins?
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.
