A Workshop of Horrors

The Shell Shock online slot comes from Rival Gaming, a slot provider based in Cyprus.

Taking place in the depths of a deranged scientist’s lab, the Shell Shock slot machine is a horror-themed exploration of science gone wrong, very wrong. Game symbols include beakers full of green liquid and grotesque experiments. Visually, the game is incredible. It looks like something straight from a classic comic book.

Enjoy Electrifying Features

You can play the Shell Shock slot online with bets of anywhere between 0.15 coins and 18.75 coins.

The Shell Shock logo acts as the wild symbol, substituting for all symbols except scatters. Every win involving a wild receives a 2x multiplier.

The Frankenturtle scatter symbol is your key to the biggest rewards in the Shell Shock online slot. Landing three or more scatters anywhere on the reels triggers 10 free spins while also awarding instant cash prizes: three scatters pay 1x your bet, four scatters award 3x, and five scatters deliver 100x your total bet.

The game has a below-average RTP of 93.95% and medium volatility.
