Cash Tank — Play Free at Rune Riches

Cash Tank is Endorphina's take on the gem-led video slots — and it lands more confidently than a lot of recent releases.

Under the hood, Cash Tank runs at 96% return-to-player, in line with the industry-typical range. The pacing comes from low variance (3/10), making it a strong pick for longer relaxed sessions. 10-payline layout keeps the wins legible without burying you in overlap..

Endorphina have built a reputation for clear visual hierarchy, and Cash Tank 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.

Play Cash Tank risk-free at Rune Riches with our dual-currency model. Sweep Coins can be redeemed for prizes; Gold Coins are pure entertainment.
