Rainbow Jellyfish — Play Free at Rune Riches

Released in 2025, KA Gaming's Rainbow Jellyfish pairs an atmosphere that pulls you in within seconds with the kind of polish you expect from a studio at the top of its game.

Under the hood, Rainbow Jellyfish runs at 96% return-to-player, in line with the industry-typical range. The pacing comes from a middle-of-the-road 4/10 volatility that suits most playstyles. 20-payline layout keeps the wins legible without burying you in overlap..

KA Gaming have built a reputation for reliable maths, and Rainbow Jellyfish sits comfortably in that lineage. Mobile and desktop versions feel effectively identical — touch targets are sized for thumbs, animations remain smooth on mid-range hardware, and the audio mix scales down gracefully without headphones.
