Mermaid's Diamond

Mermaid’s Diamond by Play’n GO is a 5-reel video slot set in a deep-sea theme, released in September 2017. The game uses 720 ways to win, with matching symbols paying from either the leftmost or rightmost reel. The paytable includes sea-themed icons, jewels such as rubies, emeralds and diamonds, plus a mermaid wild symbol.

When two or more mermaid symbols land on the same reel, the wild expands to cover the full reel. Poseidon can also appear with a trident feature that adds extra wild symbols during a spin. Bonus play is triggered by five treasure chest symbols anywhere on the grid, unlocking up to 25 free spins, while four chests may still lead to a bonus if the missing chest is created by Poseidon.

This demo version lets players play for free and practice before playing for real money. During free spins, collecting five diamond symbols can activate Trident Wilds, and three or more chests may extend the round with additional spins. The slot is listed with low-to-medium volatility and a wide betting range.
