Retrigger

A retrigger occurs when you land the trigger symbols again during a free spins round, awarding additional free spins on top of those still remaining rather than starting a new round. The triggering symbols are usually Scatters, though some slots use a dedicated bonus symbol. The number of extra spins awarded on a retrigger is often the same as the original trigger, and many games place no cap on how many times a round can retrigger, so a single feature can, in principle, run for a very long time. Worked example: three Scatters award 10 free spins. On spin 4, three more Scatters land and retrigger the feature, adding another 10 spins to the 6 you had left, giving 16 remaining. If a further retrigger occurs later, another 10 are stacked on. In a slot with a 2x free-spins multiplier and a £0.50 stake, extending the round this way multiplies your exposure to those enhanced-value spins without any additional cost, which is a major driver of the feature's headline win potential. Why it matters: retriggers are one of the main reasons free spins rounds produce the outsized results shown in slot promotions, but they are governed by the game's RNG and cannot be influenced by the player. As an affiliate or player, note that a high maximum-win cap can quietly limit the practical benefit of a long retriggered run. The common mistake is expecting frequent retriggers because a paytable advertises them. In high-volatility slots retriggers are rare, so treat them as an occasional bonus, not a reliable outcome. Compare with free spins, the scatter, the multiplier and respin.
