King of Atlantis Slot Machine

Are you up for a challenge? If so, come and meet King of Atlantis himself, trident included! Here, we have a totally free version of this IGT classic. This aquatic video slot offers wavy casino fun across 5 reels and 40 lines, and as many have noticed, it tends to favour high-stake bettors, due to the payout format.

Stories of the lost city of Atlantis have made countless underwater adventures more exciting. Inspired by the legend of Poseidon's capital, IGT has made a striking, dynamic video slot machine and called it King of Atlantis.

Mixing mythology with fiction, IGT tells a story of Poseidon guarding Atlantis' riches. The key word here is 'riches' — that's good enough to attract any gambler. We're all underwater treasure hunters whenever the opportunity arises. The visuals of King of Atlantis are expertly crafted; the reels are mounted against a sea bottom background which overflows with gold. The game has 5 reels and 5 rows — a slightly unusual 5x5 reel grid configuration for an IGT slot. Wins are formed across 40 fixed paying lines.

Real Money Payouts

The RTP ranges from 92.01% to 96.14% and the top base game real money payout belongs to a combo of 5 mermaids (250x the stake payout).

You can't adjust the number of lines but you can set the size of your total bet and you can also choose the amount of Wilds that will appear on screen. Throw in more coins into the fountain, and you'll enjoy the opportunity to have extra Wilds added into play. That's optional, though, and comes across as a clever and creative accessory to a well-rounded game. All symbols are theme-related, no generic playing cards here! Stand back for splashes of symbols: harps, amphorae, seashells and magical stones, jewellery, dolphins and red-haired mermaids. Poseidon himself is the Wild and his potent trident is the Bonus symbol.

The Gigantic Wilds are one of the main reasons King of Atlantis differs from most underwater-themed slot games. Poseidon pops up on reels 2 and 4 and appears two reels wide. If you have some cash to spare, then you can include more Wilds into the mix and really make friends with the Olympic deity. How many people can say they've done that?

More profit can come from free games. Landing 3 trident icons is not the way to trigger free spins, mind you. That's the big twist! You need only one trident Bonus symbol on reel 1 and a Wild anywhere else. This combo will induce 8 extra spins. The Wild or Wilds that activated the feature will stay in position during the free spins round. Unfortunately, there is no way to re-trigger more free spins. The machine is also deprived of standard Scatter icons and also of a Gamble and Autospin features. These cuts probably needed to be made in order to make way for other, more appealing features.

Graphically advanced, with all its twists and turns, King of Atlantis is one of more creative and innovative IGT slots of late. It is a high variance game, which means it can flood your balance faster than you can lay your eyes on the horizon. One needs to be careful both with bet size and Wild number adjustments. As long as you play big, you can win bigger, but always spin the reels with caution.

Frequently Asked Questions

What is the RTP of King of Atlantis?

King of Atlantis has an RTP (Return to Player) ranging from 92.01% to 96.14%, depending on casino configuration. Players should seek out casinos running the higher setting. The game runs at high variance, so wins are infrequent but can be substantial — particularly when Gigantic Wild Poseidon symbols cover reels 2 and 4 simultaneously.

Can I play King of Atlantis for real money?

Yes, King of Atlantis is available as a real money slots game at online casinos powered by IGT. The top base game payout is 250x the stake for five mermaid symbols. Players also have the option to pay for additional Wild symbols to appear on the reels — a unique real money mechanic that allows players to actively increase their winning chances at a cost.

How many paylines does King of Atlantis have?

King of Atlantis features 40 fixed paylines across an unusual 5x5 reel grid — larger than IGT's standard 5x3 or 5x4 formats. All symbols are theme-related with no generic playing cards, and Poseidon appears as a Gigantic Wild covering two reels wide on reels 2 and 4.

How do I trigger Free Spins in King of Atlantis?

Free Spins in King of Atlantis are triggered by landing one trident Bonus symbol on reel 1 alongside any Wild symbol elsewhere on the reels — not the traditional three-Scatter method. This awards 8 free games. The Wild or Wilds that triggered the feature remain sticky in their positions for the entire duration. The feature cannot be retriggered.

What are Gigantic Wilds in King of Atlantis?

Gigantic Wilds in King of Atlantis are oversized Poseidon symbols that appear two reels wide on reels 2 and 4. When they land, they simultaneously substitute for symbols on both reels, dramatically increasing the number of winning combinations formed. Players can optionally pay extra coins to increase the frequency with which these Gigantic Wilds appear.

What makes King of Atlantis unusual among IGT slots?

King of Atlantis stands out for several design choices unusual in the IGT catalogue: a 5x5 grid (vs the typical 5x3 or 5x4), no generic playing card symbols, a non-standard free spins trigger requiring only one trident plus any Wild (rather than three Scatters), Gigantic two-reel-wide Wilds, and an optional paid Wild enhancement mechanic. Together these elements give it a significantly different feel from most IGT land-based conversions.
