Swoll — RTP, volatility and max win

Swoll by Shady Lady goes for a loud American theme: sports, fast cars, drinks and plenty of flames. Wins run on ways rather than lines, and wilds with multipliers can nudge into position.

Swoll came out on September 15, 2025 and has the swagger of a sports bar: cars, drinks and sporting symbols against a fiery background. The game uses 5×4 reels and 1,024 ways, with no fixed lines. A wide stake range of €0.10 to €100 covers small rounds and very high bets alike. You can also switch on a bonus bet.

If you like the high volatility of Swoll and its big ceiling, the list of inferno slots by volatility points to games with a similar profile.

Matching symbols pay across neighbouring reels from the left, in any row. Every combination across the 1,024 ways is paid at once. Symbols can land stacked and fill whole reels, which sharply raises the number of hits per spin. Wilds stand in for missing symbols, and a multiplier on a wild applies to every way it completes.

Nudges and wild multipliers: wilds can nudge along the reel until they are fully in view, and they bring a multiplier with them.

Expanding and stacked symbols: symbols can stretch across a reel or land stacked, serving many ways at once.

Free spins: scatters trigger them, and a multiplier boosts wins during the round. More free spins can be added.

Bonus bet and bonus buy: a higher stake improves the chance of the bonus, or you can buy the free spins outright.

Because the wild multipliers in Swoll apply to every way they complete, a comparison with other inferno slots with ways to win makes sense.

RTP 96.2%, higher than 74% of the 400 Inferno slots. Background: how RTP works on a slot. Volatility High, like 85 of the 182 slots in the Fire & flame theme. Background: what slot volatility means. Max win 20,000× (€2,000,000 at the highest stake). Background: what max win means on a slot.

With 96.2%, Swoll is in the upper third of the Inferno slots.

The 20,000× biggest prize is among the leaders, with about 92% of the collection sitting lower. With high volatility, that figure needs several wild multipliers and the free spins multiplier to come together in the same round.

Since the ceiling is what Swoll is all about, the max win comparison shows which games reach even higher.

Also with flames on the reels, high volatility along with a roughly equivalent RTP, like Swoll:
