Mermaid's Diamond

Play'n GO has 494 games in our catalogue and a recurring habit of shipping multi-RTP builds. This one follows the pattern. The 96.5% we display is the default configuration, with the remaining tiers documented outside the summary record.

A 500,000 cash cap and a 0.20–100 bet range

Variance sits at 3 of 5, the middle grade on our scale. Its top payout arrives as a flat 500,000 in cash, never a multiplier, so the same fixed limit applies at 0.20 per spin and at 100. Layout is five reels under Fixed paylines, and the mechanics record stays blank: Megaways, bonus buy, progressive pools and cascading symbols are all missing. Against the 96.08% median we calculate from 9,233 catalogued returns, that 96.5% default sits comfortably ahead, with slot.report the only feed reporting it.

Ocean and mermaid art on plain machinery. It suits a mid-variance session across a wide stake range, and anyone uninterested in feature shortcuts.

Whatever a session does, 3.5% of turnover is the operator's long-run margin. Set a limit and treat it as final. 18+.
