How free spins rounds work
Free spins here are part of the game, not a casino offer: they are triggered inside the slot and played at the bet that triggered them. Their value is already included in the game’s RTP.
In many modern slots most of the potential sits in the free spins, which is why the base game can feel quiet between bonuses. Check the volatility of each game below.
RTP of free spins slots
The highest headline RTPs among free spins slots are Jack in a Pot by Red Tiger (98.18%), Revolvero by Red Tiger (98.11%) and The Catfather by Pragmatic Play (98.1%). The average headline RTP across all 876 is 96.22%, and the lowest is 91.93% on Hockey League.
145 of them (17%) are published in more than one RTP version, so the return depends on the version an operator runs. The widest gap is on Mystery Joker: from 96.98% down to 83.99%.
Volatility and max win
Volatility is published for 575 of the 876 games: 47 low, 112 medium, 188 high and 228 very high.
The largest published max wins are 500,000× on Tombstone Slaughter: El Gordo's Revenge, 300,000× on Tombstone R.I.P and 200,000× on San Quentin 2: Death Row. The median max win of the 508 games that publish one is 8,200×. A max win is a rare ceiling, not a result to expect.
