Secrets of Atlantis by NetEnt is a five-reel, four-row slot with 40 both-ways paylines, where wins can start from either the left or right side. The game has a 97.07% RTP and medium volatility, with stake controls based on coin value and level. Players can use the demo version to play for free and practice before playing for real money.
The symbol set combines sea creatures such as jellyfish, turtles and crabs with higher-paying jewel versions and Oyster’s Pearl as the top symbol. A Mermaid Nudge Wild can appear partly on the reels and then move to cover the full column. Matching three or more symbols on an active payline produces a win, with larger payouts for five-of-a-kind combinations.
The main feature is the Highlight Feature, which marks sections of reels two, three and four. If all three middle reels are fully highlighted, a Re-Spin with Colossal symbols is triggered, introducing a 3x4 symbol block in the centre of the grid. The maximum win is 4,000 times the coin value.
