Tower of Atlantis – Descend Into Poseidon’s Lost City
Tower of Atlantis is a deep-sea-themed slot set in the ruins of the legendary lost city. Poseidon sits beside the reels among old Greek structures, coral and plenty of underwater scenery. This PokerStars slot keeps the Atlantis theme pretty traditional, but it’s the base-game features that make it stand out.
The normal game includes Wild Multipliers and the random Poseidon Spins Multiplier Feature, while three or more Bonus Scatter symbols can open the Tower of Atlantis Bonus. This changes the game completely, bringing in the MegaClimb feature, Advance symbols, Skulls, Restores and several prizes as the player moves further up the tower.

Theme and Design: Discovering the Lost City of Atlantis
This slot is set beneath the ocean around the ruins of Atlantis. Poseidon sits beside the reels while old Greek structures, underwater plants and other details fill the background. It’s a familiar setting for a mythology-based fantasy slot, with Poseidon fitting naturally into the underwater theme. He is also more than just part of the background, as the god of the sea has his own random feature during the base game. The symbols carry on the same theme, mixing Atlantis-themed visuals with card and shell symbols. The overall look stays pretty traditional instead of trying to completely reinvent the genre.
Almost every part of the grid is animated in this casino game, from Poseidon’s chest rising as he breathes and his hair drifting in the water to his trident giving off a soft glow. Bubbles also float up through the background, while the bubbles containing Wild symbols gently pulsate on the reels. The sound fits the underwater setting too, mixing soft ambient water effects with relaxed, plucked string music that keeps the base game feeling calm instead of stressful.
Poseidon Takes Over
The calmer look of the base game also changes when the features kick in. Poseidon becomes more involved during Poseidon Spins, while multiplier symbols moving through the reels add more movement to the grid. The Tower Bonus has a different look again, moving away from the normal underwater reels and putting more focus on the climb itself. This helps separate the base game from the bonus without moving away from the Atlantis theme. The bubbles, glowing symbols and underwater background stay in place, so it still feels like the same game even when the setup changes.
Core Gameplay: Wild Multipliers and the Atlantis Bonus
Tower of Atlantis uses five reels with four rows on each reel. Winning combinations have to have at least three matching symbols on connected reels, beginning with the leftmost reel. Only the highest win on each payline is paid. This casino game uses fixed paylines instead of Cluster Pays or a ways-to-win system.
Payline wins also use the selected bet multiplier, with the paytable showing different payouts depending on the bet. Most of the base game extras come from the Wild Multipliers and Poseidon Spins before the Tower of Atlantis Bonus changes the setup completely.
Slot Symbols in Tower of Atlantis
The lower-paying symbols include A, K, Q and J, along with two shell-style symbols. There are also four higher-paying Atlantis-themed symbols, including a trident. The Bonus symbol acts as the game’s Scatter and only show up during the base game. Landing three or more Bonus Scatter symbols during one spin triggers the Tower of Atlantis Bonus. The Wild and Multiplier Wilds handle most of the extra action during normal spins.
Standard Wild and Wild Multipliers
The normal Wild can land during the base spins of this fantasy slot and take the place of other paying symbols. It doesn’t work as a Bonus Scatter. Multiplier Wilds can also land on the middle reels, with 2x, 3x, 4x and 5x versions used to increase any payline win they form part of.

Poseidon Spins Multiplier Feature
The Poseidon Spins Multiplier Feature can start randomly during any base game spin. When it begins, up to five multipliers can be placed on the grid. Multipliers appearing on the bottom row begin at 2x, with the value increasing by another 1x for every position higher on the reels. After any line wins have been paid, the multipliers move upwards by one position and increase by +1x. The reels then respin, which continues while at least one multiplier stays on the screen.
Moving Multipliers During Poseidon Spins
The multipliers keep moving upwards instead of staying in the same spot. A multiplier that starts lower down can increase several times as it moves through the grid. Once it moves beyond the top row, it disappears. If several multipliers show up together, they can sit at different heights and carry different values during the same series of respins. The feature uses the same bet multiplier as the spin that started it.
Poseidon Spins can last for several respins depending on where the multipliers first appear. A multiplier placed near the bottom of the grid has further to travel before disappearing, which also gives it more chances to increase. One appearing higher up has fewer moves left before leaving the screen. With several multipliers active at the same time, their values can be different depending on where they are sitting. This means the grid can change quite a bit from one respin to the next as some multipliers increase, others disappear and the remaining ones continue moving upwards.
The Tower of Atlantis Bonus
Landing three or more Bonus Scatter symbols during one base-game spin triggers the main Tower of Atlantis Bonus. This is where the MegaClimb feature triggers. The bonus can use up to five active reels, with three positions on each reel. The number of reels that begin active depends on how many Scatter symbols triggered the feature.
Any reels that don’t begin active are switched off. Skulls can also disable active reels as the bonus continues, while Restore symbols can bring them back. The feature keeps running while at least one reel stays active.
MegaClimb: Climbing the Tower
MegaClimb sits at the centre of the bonus. The tower includes the Grand Prize, Minor Prize, a Variable Multiplier starting at 10x, plus separate 5x, 3x and 2x multipliers. Advance symbols move progress further up the tower, with each Advance moving it forward by one position.
Reaching three Advances activates a Tower Multiplier. Reaching 15 Advances activates the Minor Prize. And reaching 18 Advances activates the Grand Prize. Several other bonus symbols can land during the feature, increasing prize values, adding to the Variable Multiplier or changing how many reels stay active.
The number of active reels also matters throughout the climb. Skulls can gradually reduce the grid as the bonus continues, leaving fewer reels spinning and fewer places for Advance, Prize Increase or Restore symbols to land. A Restore can reverse some of that by bringing one reel back, but there is no guarantee one will appear before the remaining reels are switched off. This gives MegaClimb a different structure from a normal Free Spins feature. There’s no set number of spins to work through. Instead, progress depends on how long the reels stay active and how many Advance symbols land before the last one is disabled.
Credit Prize Symbols
The Credit Prize symbol can land during the Tower Bonus. At the default £1 bet, Credit Prize values work out at the equivalent of 0.2x to 6.64x the bet. At the end of a bonus spin, any Credit Prize that has landed is multiplied by the Tower Multiplier active at that point.
When Does the Tower of Atlantis Bonus End?
Unlike a traditional Free Spins feature, the Tower Bonus doesn’t start with a fixed number of spins. It continues for as long as at least one reel stays active. Once every active reel has been disabled, the bonus finishes. If the Minor or Grand Prize has been activated during the climb, it is paid at the end of the feature.
Prize and Multiplier Increase Symbols
The Prize Increase symbol increases the value of the Minor Prize. When played on PokerStars at a £1 bet, each increase is the equivalent of 1x to 7x the bet, while the Minor Prize itself can range from 140x to 217x the bet. The prize is only awarded if the player reaches 15 Advances.
The Multiplier Increase symbol works on the Variable Multiplier. This starts at 10x and can reach 31x. Each Multiplier Increase can add between +1x and +5x. More than one can land during the same bonus, allowing the Variable Multiplier to increase further as the feature continues.
Bonus Symbols: Skulls, Restores and Blanks
Skulls work against the player during the Tower of Atlantis Bonus. When a Skull lands, the reel it appears on is switched off. That reel then stops spinning unless a Restore symbol later brings it back. Several Skulls can gradually leave fewer reels in play, and the bonus ends once there are no active reels remaining.
The Restore symbol can bring one of the disabled reels back into play. Once restored, that reel can begin spinning again. This gives the feature a way to bring back reels that have already been switched off by Skull symbols. Blank symbols can also show up during the bonus. They don’t have a payout or trigger another feature, they just fill a position during that particular spin.
Final Thoughts: Climb Poseidon’s Tower
Tower of Atlantis, played on PokerStars, is an underwater fantasy slot built around Poseidon, Atlantis and the climb through the lost tower. The base game keeps things pretty simple, while Wild Multipliers and Poseidon Spins add more before the main bonus begins. The Tower Bonus is where the game really changes pace, with MegaClimb, Advance symbols and the battle between Skulls and Restores giving the feature a lot more depth.
