Unfortunately, the RTP value sits pretty low for this slot. Some popular online slots have an industry average of 96% while the best online slots have RTPs as high as 98%.

Highest payout

The highest prize could be the jackpot prize which is up to 2,000 coins. In the game, the wild symbol offers a massive win chance of up to 1,000x your bet. However, regular game symbols will only pay out a maximum of 80 times your bet, which would require landing the sevens symbols.

Diamond Double slots feature several symbols that you will have to combine on the reels to trigger a win. These symbols will pay based on their value and number of combinations.


Different features of Double diamond slots

Wild symbols
