Mermaid's Diamond slot by Play'n GO

How Mermaid's Diamond works

Two or more mermaids on a reel make her cover the entire reel, and Poseidon can randomly create extra wilds. Five treasure chests anywhere let you unlock a chest to reveal up to 25 free spins, and in free spins five diamonds summon Trident Wilds.

Before you play

Check the in-game paytable first so you know which symbols matter most. A demo uses the same rules and maths as the real-money version, only with virtual credits.
