King of Atlantis

King of Atlantis is an IGT online slot that's inspired by the legend of the lost city of Atlantis that supposedly lies at the bottom of the Atlantic sea near the Pillars of Hercules.


Although the city has never been discovered by a human, IGT gives you the chance to explore it in all its glory. And, while you're swimming with dolphins and mermaids, and rubbing shoulders with Neptune (the Greek god of the sea), you could be turning up a variety of valuable treasures with the slot's many paytable symbols. There's also a Free Spins Bonus where you can win big with Gigantic Wilds, all for as little as 40p per spin.

Appearance and Sound Effects

King of Atlantis reveals a part of the ocean that many of us will never get to see in our lifetimes. The seabed is littered with gold coins, and plant life grows over the ancient and empty buildings that were once part of the legendary city of Atlantis. Sunlight streams from the surface to penetrate the very bottom of the ocean floor, making the piles of gold coins that lie upon it glitter even more brightly. A thunderous orchestral soundtrack charges the calm underwater atmosphere with excitement, and as each winning combination is formed, your screen lights up as the symbols become enlarged and animated.

The paytable symbols that can help you create wins and gain prizes in the King of Atlantis slots game are Neptune, the Dolphin, the Mermaid, the Harp, the Ring, the Crown, the Seashell, the Vase, Neptune's Trident, and the Pebble.

Bonuses and Special Features

As a mythology-themed slots game, King of Atlantis is hard to beat as it's packed with thrilling special features that are designed to push your winning potential to the max.

To begin with, there's the wild symbol which is represented by the Greek god Neptune – the King of Atlantis – but it's not just a regular wild symbol as it appears two reels wide on Reels 2 and 4, and also replaces adjacent symbols to its right to
form a Gigantic Wild. Land the bonus symbol (Neptune's Trident) on the first reel and a Gigantic Wild anywhere else, and you'll trigger the Poseidon Free Spins Bonus. The Bonus awards eight free spins with at least one Gigantic Wild appearing on every spin. In addition, the wild that triggered the Poseidon Free Spins Bonus stays in place for the duration of your free spins.

By default, you can get up to twenty wilds on the reels at any one time, but by upping your stake by 25 or 50 credits, you can have forty or sixty wilds in play respectively.

Paylines/Reels

King of Atlantis uses five reels, five rows of symbols, and forty paylines, and has an RTP (Return to Player Rate) of between 92.01% and 96.14%.

Mobile Compatibility

The game is designed to work with desktops, laptops, mobile phones, and tablets, and includes mobile-friendly game controls when played on mobile devices.
