Play King of Atlantis Slot For Free

IGT’s King of Atlantis slot is not exactly bringing a new theme to the online slot machine gaming world. However, this slot machine game does contain a rather extensive free spins feature which is certainly new for the online casino software developers and does make King of Atlantis stand out.

King of Atlantis is themed on Atlantis and the legendary Atlantean civilisation. Expect to find plenty related to Poseidon in this slot.


IGT are famed for their land-based slot machine games, as well as their online slots. This game has been developed to be mobile friendly, a trend becoming ever more popular in IGT developed slots.

Whilst IGT normally keeps things simple, the King of Atlantis slot machine offers something considerably more challenging to players than we are ordinarily used to seeing from this developer.

How to play

Players will find that there is a total of 40 paylines spread over the 5 reels of this slot machine game, but none of those can be altered by the player.

Ordinarily, this would give the King of Atlantis slot a wagering range which stems from $0.40 per spin, up to $800 per spin. However, there is an added bet feature, which can increase the number of wilds which appear on the reels. This costs more and can see your bet range from $0.90 up to $1,800 a pop should you choose to play with it.


Wild symbols: Wild symbols are extended in this game. Known as Gigantic Wilds, they appear as Poseidon and can substitute for all other symbols in the slot, except for the scatter icon. These wilds can occupy two reels at once, but can only be found on the second and fourth reels. Should wilds appear on the second reel, they will extend to the third, and if they appear on the fourth reel, they will extend to the fifth.

Extra wilds: There are ordinarily 20 wilds on the reels with a standard bet. This can be increased to 40 or 60 wilds if you play with extended bets. A total of 40 wilds can be yours for wagers which range from $0.60 up to $1,300, whilst playing with all 60 wilds on the reels costs you between $0.90 and $1,800 per spin, as stated earlier.

Poseidon free spins: The Poseidon free spins feature is triggered by landing bonus scatters on the first reel and a Gigantic Wild symbol on the reels.

Players will initially be rewarded with a total of 8 free spins. Gigantic Wilds appearing during the free spins bonus will be held in place for the duration of the feature, which cannot be retriggered. On the plus side, you could end up playing with the second, third, fourth and fifth reels fully wild, which will do wonders for your winnings.

Maximum pay-outs

Funnily enough, the top prize in this slot machine game is rather petite. With a bit of luck, players can scoop wins worth up to 250x their total bet. The small non-progressive jackpot is likely a result of there being so many other decent features, and colossal wilds present in this slot.


King of Atlantis won’t blow you away, but there is enough in this IGT developed slot to make it stand out from the other Atlantean-themed slot machines on the net. We did find the Gigantic Wilds rather alluring, but the cost to use them is a bit on the steep side and may put players with smaller budgets off.
