Atlantis online slot game

Atlantis by Red Tiger Gaming is an underwater-themed slot featuring cascading reels and treasure chest multipliers paired with wild reels. The free spins round can build to unlimited multipliers, and the review describes potential returns of up to 5,000x the spin bet on a spin.

Theme and Storyline

Journey beneath the waves to explore Atlantis, where treasure awaits among golden waters and across the ocean floor.

Graphics, Sound, and Animation

The review singles out Red Tiger Gaming’s crisp visuals and animation. Atlantis Treasure uses bright underwater colours, with reels filling a desktop display or mobile screen inside a narrow frame showing the sandy seabed. Animated details, gentle effects and a slow aquatic soundtrack help create the mood of a sunken city.

Gameplay

Atlantis has a 5x4 reel grid and 30 paylines. Its 4 rows allow symbols to connect from left to right across neighbouring reels. The review highlights wild reels with random multipliers and a bonus free spins round that can retrigger as ways to pursue larger wins.

Standard symbol combinations pay in both the base game and bonus, as in many online slots. A winning sequence starts on reel 1, so a 4-symbol match spans reels 1-2-3-4. After a match lands, the reels cascade.

Regular symbols need to connect in groups of 3, 4, or 5 along a pay line. The spin-bet multipliers for 5 symbols on a pay line are:

  • Gold Cityscape - 5x
  • Gold Goblet - 4x
  • Gold Telescope - 3x
  • Seashell - 2.5x
  • Anchor - 2x
  • Playing Card Symbols – From 1.2x to 0.5x

A wild symbol substitutes for regular symbols and can help complete combinations in Atlantis.

Bonuses and Free Spins

Cascading Reels: After a winning combination, its symbols vanish and new ones drop into place. Any further combinations formed by the cascade also pay; enough scatter symbols from a cascade can trigger the ‘Gold Spin’ feature.

Treasure Chest: A chest at the base of a reel can expand into a full stack of wilds, 1x4 symbols high. It also awards a random multiplier of up to x5 for combinations it helps create.

Gold Spins: Landing 3 ‘Gold Spin’ symbols triggers the free spins round. The review says that whenever the ‘Treasure Chest’ creates wild reel stacks, the multiplier rises by 5, with no stated limit to the number of increases.

Gold Spin Re-Trigger: During the bonus, each ‘Gold Spin’ symbol becomes a SPIN symbol. Every SPIN symbol that lands awards up to 8 additional free spins.

Bet sizes, RTP and variance

The -/ ‘STAKE’ control sets a wager between 0.20 and 20.00 per spin. The review directs readers to open the ‘?’ section and scroll to the end of the rules page to find the RTP, which it lists as 95.77%. It also cites Red Tiger’s website as classifying the game as high variance.

Conclusion

The review highlights Atlantis by Red Tiger for its detailed visuals, animation and cascading reels, as well as wild reels with multipliers. A SPIN symbol can add to the free spins bonus. The review reports a top outcome of 5202.8x the spin bet; this is a claim, not a guaranteed result.
