Extra Spins games add more bonus spins through scatters, meters or re-triggers. Our 124-game catalogue in 2026 lets you test the feature in free demos before staking real money.
Extra Spins are bonus awards that add more spins after a trigger, usually through Scatter symbols, collection meters or a re-trigger inside Free Spins. Some studios call them bonus spins, added spins or extensions, but the job is the same. In 2026, the catalogue has 124 games, and I can see why they are popular: the feature is clear, pays visibly, and keeps the maths easy to follow.
How the trigger behaves
Three Scatter symbols are the common route, though Blueprint often ties extra awards to fishing bonuses or collection rounds, while Kalamba Games uses feature trails and symbol upgrades. The trigger is predictable enough to understand, but not guaranteed on demand. You know what must land, and the slot tells you before the balance takes the hit.
Retriggers matter more than the opening award. I prefer games where added spins arrive with a visible meter or collected symbols, because dead bonus rounds feel rough at low stakes. Strong examples push multipliers during the extension, so a late re-trigger can turn an ordinary result into the session's main win. Aye, the ladder is plain, but it is fair enough.
Games worth testing
Play'n GO leads the cleanest side of the category. Book of Dead gives a familiar 10-spin round with expanding symbols, while Reactoonz builds charge towards bigger bonus phases. Rise of Olympus is harsher, but the multiplier growth has real bite. I rate these because the trigger logic is easy to read, not hidden behind fluff.
Max-win figures are stronger elsewhere. Razor Shark is the high-ceiling pick at up to 50,000x, Sweet Bonanza reaches 21,100x with multipliers in Free Spins, and Jammin' Jars is a strong RTP shout at 96.83% with a 20,000x cap. Fishin' Frenzy and Big Bass Bonanza are plainer, but the collector-style extra awards make the gains obvious.
RTP and max-win reality
Average RTP sits at 96.19%, which is solid for a bonus-led group and slightly above the line I expect from many licensed UK lobbies. The average max win is 14,055x, but I treat that as a rough signpost, not a selection rule. One 50,000x game can bend the mean. High volatility is the real price of the bigger extensions.
FAQ
What is an Extra Spins game?
An Extra Spins game adds more bonus spins after a trigger, often through Scatter symbols or a re-trigger during Free Spins. Book of Dead and Big Bass Bonanza show the idea clearly.
Can you play these games free?
Free demos are available for the 124 games in this category, with no sign-up needed on the demo page. I would test the trigger, bonus pace and stake range before moving to real-money play.
How often do extra spins trigger?
Frequency depends on the slot's paytable, scatter rules and bonus structure, so there is no safe universal spin count. Reactoonz uses charge-based progress, while Sweet Bonanza relies on the Free Spins bonus and its multiplier hits.
What RTP should I expect?
Average RTP for the category is 96.19%, which is fair by UK slot standards. Jammin' Jars is a stronger example at 96.83%, while Book of Dead sits close to the category line at 96.21%.
Which providers use this feature most?
Play'n GO, Kalamba Games and Blueprint are the leading providers in this catalogue. Their games use different routes, from scatter-led Free Spins to collection bonuses and re-triggered awards.
