Thematics and Design: The game is set in the majestic, sunken ruins of Atlantis, with towering columns and ancient magic surrounding the reels. The design is grand, mysterious, and atmospheric, perfectly capturing the legend of the lost city.

Graphics and animations: The graphics are superb, with a detailed and realistic art style. The animations are a highlight, especially the powerful trident striking the reels to make them rise and the thrilling bonus game sequence. It’s a visually spectacular mobile slot.

Sound Accompaniment: A deep, mysterious, and cinematic orchestral score plays, creating a sense of wonder and epic scale. The sounds of bubbling water, crumbling stone, and magical chimes during features make for a highly immersive audio experience.

Regular Symbols: The low-paying symbols are the four card suits carved from stone. The five high-paying symbols are ancient Atlantean artifacts: a lyre, a vase, a shield, a helmet, and a golden disk. The disk is the most valuable symbol.

Special Symbols:

  • Trident Symbol: This is the key symbol. Landing it raises its reel by one position.
  • Scatter Symbol: A seashell is the Scatter. Landing three or more triggers the Free Spins feature.

Diving into Atlantis is simple. Set your bet, then press ‘Spin’. The main goal is to land Trident symbols to expand the reels and trigger the Jackpot Game. To see the full power of the Gigarise mechanic, we recommend trying the free slot machine demo on our site. The game is fully optimized for a deep-sea quest on all iOS and Android devices.

Gigarise Feature

This is the core mechanic. The game starts on a 5×3 grid. When a Trident symbol lands on a reel, that specific reel will grow by one row. Reels can expand up to a maximum of 8 rows high. The number of ways to win increases with every expansion, up to a massive 32,768.

Jackpot Game

When a reel reaches its maximum height of 8 rows, the Jackpot Game is triggered on that reel. A bonus reel appears, containing cash prizes (Bronze, Silver, or Gold) or one of the five progressive jackpots (Forgotten, Rare, Mythical, Ancient, or Legendary). You are awarded one spin on this bonus reel to determine your prize.

Free Spins

Landing 3, 4, or 5 Scatters awards 20, 40, or an incredible 80 free spins, respectively. The Free Spins round starts with a partially expanded reel set. The advantage here is that the reel heights you have achieved do not reset between spins, making it much easier to reach the maximum height and trigger the Jackpot Game multiple times.


RTP: The RTP of Atlantean Gigarise is 96%. This is a solid figure, especially for a progressive jackpot slot, as it includes a 3.8% contribution to the jackpots.

Volatility: This is a high volatility casino game. The gameplay is a thrilling chase to expand the reels. While the base game can be a grind, the potential to trigger the Jackpot Game at any moment, and especially during the lucrative free spins, creates immense excitement and the chance for life-changing wins.


Atlantean Gigarise is a fantastic and innovative jackpot slot. The Gigarise mechanic is a brilliant way to build suspense and link the base game directly to the jackpot chase. The theme is executed with stunning cinematic quality. For players who love progressive jackpots and innovative reel mechanics, this is a legendary quest worth undertaking.
