Retrigger slots explained
Retrigger slots are games where a bonus round can fire again while it is already active, most often inside Free Spins. Land the right symbols during the feature, and you get extra spins, a reset, or another bonus layer on top. That loop is why players rate them. You get more time in the part of the game that usually pays best, and the wins can snowball fast when multipliers stick around.
What actually counts as a re-trigger feature?
Most of the time, the trigger is simple. Hit more Scatter symbols during Free Spins, and the game adds extra spins. In some releases, the re-trigger also boosts a multiplier, upgrades wilds, or unlocks another reel modifier. I usually treat all of those as part of the same category, because the point is the same, the bonus keeps itself alive.
Good examples are Book of Dead, Starburst XXXtreme, Big Bass Bonanza, Fire Joker and Rise of Olympus 100. Some use classic scatter re-triggers, others tie them to sticky modifiers or rising multipliers. Not every release gets this right. A few games tease the feature, then make the bonus feel too short unless luck lands early.
87 games, and the best ones to try first
87 games is a healthy pool, so I’d start with proven names from Play’n GO, NetEnt and Quickspin. For classic bonus-chasing, Book of Dead still holds up. For old-school free spin energy, Gonzo's Quest and Starburst are easy entry points. If you want something louder, Reactoonz and Rise of Olympus 100 can stack momentum quickly.
For stronger upside, I’d look at Dead or Alive 2 and Big Bass Bonanza. They sit closer to the high-volatility end, and the volatility can be punishing, but the bonus rounds have proper bite. If your focus is max potential, this category average sits at 8,255x, which is enough to make re-trigger hunting feel more than cosmetic.
Are RTP and volatility good in this category?
96.32% average RTP is a decent mark for this kind of slot. It tells me the category is not built only on hype. You can find steady options, but a lot of the appeal comes from variance inside the bonus. Base games often feel quiet, then a re-triggered feature does the heavy lifting.
That means bankroll swings matter. Games like Dead or Alive 2 and Book of 99 can look brilliant on paper, especially if you care about return, but the ride is not gentle. On the flip side, lower-pressure picks such as Starburst or Fire Joker are easier to read, even if their top-end punch is lighter.
