Manta Mayhem slot by Play'n GO

How Manta Mayhem works

Clam the Prize can trigger at random during Pearl Collection. You pick a clam to reveal the number of Free Spins and Boosters, then pick pearls from eight options to uncover the Boosters, which apply throughout the round. With GO Ultra active, both the spins and the Boosters increase by one.

Before you play

Check the settings menu in the demo for autoplay and speed options before you begin. A demo uses the same rules and maths as the real-money version, only with virtual credits.
