Secrets of Atlantis is a 2016 NetEnt slot that explores the sunken city theme with a restrained elegance that suits the underwater setting. It is one of the studio’s quieter releases, but a strong RTP and an interesting wild mechanic keep it relevant.

The game runs on 243 ways to win without a fixed payline structure, set against an ocean-floor backdrop with art deco architecture suggesting a lost civilisation. Bets run from $0.20 to $400 per spin, covering a broad range. The adventure-themed visuals have a depth and polish that still look good against newer competition.

The Wild Atlantis symbol is a 2×2 block that covers four positions at once, creating larger clusters of wilds than the standard single-symbol variety. During Free Spins, the Nudge Wild mechanic comes into play — expanding sticky wilds that are partially in view get nudged into full reel positions, keeping them locked in place for the remaining spins. The combination of large wilds and the nudge mechanic can stack up meaningfully in a good Free Spins run.

The RTP of 97.07% is genuinely outstanding — among the highest in NetEnt’s catalogue — and medium volatility keeps the experience smooth rather than brutal. Max win is 700x your stake, which reflects the game’s focus on consistent returns rather than rare extreme payouts.

Secrets of Atlantis is a game for players who value reliable performance over variance. If a high RTP matters to you and you are happy with measured wins rather than jackpot swings, this is one of the best options around.
