Diamond

Diamond slots lean towards the classic end, with gems sitting where the fruit used to be. Pragmatic Play’s Diamond Strike is the plainest example. Its demo rules give 96.48%, while the official page lists 97.02%, a reminder that RTP depends on the version an operator runs. Gem Trio pushes a 3-reel layout to 20,000x, and Playson’s 4 Supershiny Diamonds adds a Charge diamond that splits into fresh diamonds and jackpots during the bonus.

Blueprint’s Triple Action Cash Strike and Light & Wonder’s Blazing 777 2x 3x 5x Cashways both run at 94%, so compare RTPs before you settle on one. Betsoft’s The Auction House takes diamonds upmarket, with every lot priced in multipliers.
