Atlantis

Fixed paylines across five reels form the whole mechanical frame of Atlantis. Red Tiger Gaming, a studio with 367 games in our catalog, left every optional engine we track switched off here: winning symbols stay put, and there is no bonus purchase. What remains is a base game carrying a very-high volatility tag. Bets run 0.1 to 20.

Very-high swings under a 95.77% return

Slot.report records the RTP at 95.77%, unverified, and files the volatility as very-high, which maps to level 5 on our scale. Two numbers matter together here. First, 95.77% falls 0.31 points under the 96.08% median that 9,233 catalogued games produce, so the long-run return is a shade below par. Second, the top-end volatility means results cluster around rare larger hits with many empty spins in between. No maximum-win figure exists in our records, so we do not quote one, and the packet has no theme tag or release date either. The 20 bet cap keeps absolute exposure per spin modest even at the ceiling.

This one is for players who accept a below-median return in exchange for a level-5 variance profile at contained stakes.

The margin at 95.77% comes to 4.23% of stakes over time, the operator's cut rather than a target to beat. Decide your limit first. 18+.
