Shells 'n Swells — RTP, volatility and max win

Genii takes Shells 'n Swells to the beach: shells, conches, crabs and lobsters sit on sand-coloured reels. Lines pay both ways, so a combination also counts when it starts on the rightmost reel.

The theme never leaves the shore: sand, shells and crustaceans in green and sandy shades. The beach reels are laid out 5×3 and pay along 30 paylines, and each spin takes between €0.01 and €37.50, which covers very small bets as well as bigger spins. Shells 'n Swells was released on October 24, 2019.

If you want more games with the high volatility of Shells 'n Swells, they are listed under volatility of inferno slots.

Wins form along the 30 paylines across this 5×3 field. Since the game pays in both directions, a row of symbols counts from the left reel as well as from the right, so the same line can hit twice. Wilds close gaps in a line, and expanding symbols fill a whole reel when they trigger, covering several lines at once.

Expanding symbols: a symbol stretches over its reel and links several lines in one go; combined with both-way pays, this is the strongest mechanic in the base game.

Free spins: scatter symbols lead into free spins, where a dedicated free spins multiplier boosts the wins of the round.

Pick bonus: bonus symbols open a bonus game in which you pick hidden objects on the beach to reveal your prize.

Because the expanding symbols in Shells 'n Swells cover several lines at once, the game belongs with the inferno slots with expanding symbols.

The biggest prize of 12,000× puts it in the upper fifth of the inferno slots, and volatility is high: long stretches of small hits alternate with free spins and the pick bonus, which is where the big amounts come from.
