The blue sapphire, green emerald and red ruby symbols give high bonus payouts when one or all appear on the reels. The see-through, crystal clear diamond symbol that shines brighter than all the rest in Mermaid’s Diamond slot is the highest paying symbol in the game. The free spins feature is triggered when you land 4 or more of the treasure chest scatter symbols, and once triggered, 5 treasure chests will appear on the screen. Your goal will be to click on one of them in order to reveal the number of spins you have been awarded. 3 or more scatters during this round will trigger more spins.

You can turn all the symbols on a reel into wilds by collecting five diamond symbols during the free spins round in the Mermaid’s Diamond slot. The wild symbol also randomly activates the Trident Wild feature. The Trident Wilds feature can shoot down one or two wilds at any given time to create great winning combinations for you. The treasure chest is the scatter symbol and may appear stacked on all reels to activate up to 25 free spins. There are different payout multipliers in this game too; the emerald has a 1x multiplier, the blue sapphire has a 1.5x multiplier, while the ruby has a 2.5x multiplier.
