Rival Gaming explores the depths of the ocean in Lost Secret of Atlantis. Released in 2018, this title focuses on the mythical sunken city. It uses a standard 5×3 reel layout. Most players recognize Rival for their narrative-driven “i-Slots,” but this game leans more into classic video slot mechanics. It offers 25 adjustable paylines. This allows for granular control over every spin.
The game targets fans of underwater exploration. You won’t find revolutionary 3D engines here. Instead, it provides a functional, data-centric experience. The primary draw is the complex bonus structure. Some sources cite a massive number of potential bonus game variations. This adds a layer of depth often missing from modern “one-and-done” feature slots.

📊 Characteristics and Mechanics
The technical profile of Lost Secret of Atlantis reflects its era. It is a traditional video slot with a focus on line-based wins. Below is the breakdown of the core specifications.

The RTP is 94.6%. This is lower than the modern industry average of 96%. You should expect a higher house edge over long sessions. The volatility feels medium. Wins happen often enough to keep the balance moving, but the biggest payouts are locked behind the multi-stage bonus rounds. Because the paylines are adjustable, you can play with a single cent. High rollers might find the maximum bet of $0.25 per line ($6.25 total) a bit restrictive.
✨ Theme, Graphics, and Soundtrack
The atmosphere is distinctly aquatic. The background shows the murky depths of the Atlantic. Bubbles rise between the reels. Rival used a cartoonish art style common in mid-2010s slots. The symbols are thematic. You will see oxygen tanks, submarines, sea creatures, and ancient statues.

The highest-paying symbols include the female explorer and the golden artifacts. The soundtrack is ambient. It features synth-heavy underwater tones. It doesn’t distract from the gameplay. Sound effects trigger on winning combinations. These are standard “arcade” sounds. They offer clear audio feedback when a wild lands or a scatter appears.
🎁 Bonus Features and Free Spins
Lost Secret of Atlantis thrives on its bonus content. Unlike many slots that offer a single free spins round, this title integrates multiple triggers.
Wild Submarines
The submarine symbol acts as the Wild. It replaces all standard symbols to complete a payline. In this game, Wilds often come with multipliers. If you land a Wild in a winning combination, it can double the payout. During certain phases, Wilds can expand to cover entire reels.
Free Spins Round
You need three or more Scatter symbols to enter the free spins. The Scatter is represented by the mysterious blue creature. Landing three Scatters awards 10 spins. Four Scatters give 20. Five Scatters grant 75 free spins. This is a high number compared to competitors. All wins during the free spins are usually tripled. This 3x multiplier is where the significant profit potential lies.
Secret Bonus Game
There is a dedicated Bonus symbol. If you land three or more of these symbols, a “pick-em” style game starts. You are presented with various artifacts on the ocean floor. You pick icons to reveal cash prizes. The game mentions hundreds of bonus variations. This refers to the different paths and prize pools available during these interactive segments.
