Lost Secret of Atlantis is a five-reel slot from Rival Gaming built around an underwater search for a hidden city. The game uses 25 paylines and a marine-themed symbol set that includes shells, starfish, seahorses, sharks, tropical fish, sea creatures, a crumbled ancient statue and a golden ring. The shark acts as the wild symbol and can expand to cover a reel when it helps form a win.
Players can use the demo version to play for free and practice before playing for real money. Three or more Submarine symbols trigger the Free Spins feature, which awards up to 75 spins and includes a 3x multiplier. Scatter wins are also part of the rules, with payouts based on the number of active lines.
The Bonus Round starts when three or more Sea Creature symbols appear anywhere on the reels. In this feature, a sea creature reveals three Secret Spheres, and one is selected to award coins. The slot has an RTP of 94.6% and a betting range from 0.01 to 0.25.
