King of Atlantis: The Basics & How to Play

King of Atlantis is a video slot by IGT, built with a 5-reel, 4-row setup and 40 fixed paylines. It’s themed after Atlantis, so expect Poseidon, dolphins, coral, shells, crowns, and tridents all over your screen. The “gigantic wild” system is the game’s thing. Poseidon himself lands as stacked wilds, and you can pick if you want 20, 40, or 60 wilds mixed into your reels each spin. More wilds, higher bet.

The basic gameplay? Select your wild amount, set your bet, and hit spin. The reels churn through the usual suspects but then sometimes, out of nowhere, a giant Poseidon wild blankets half the grid. There are scatter symbols too, and a free spins bonus triggers in a not-so-standard way.

Stuff I noticed (personal gripes and likes):

• Adjustable wilds are cool, but betting feels a little weird since it changes with your wild setting.
• No autoplay, so you’re pressing spin every time. Old-school vibe.
• 40 paylines are locked in, can’t tweak.
• Free spins don’t pop up as often as, say, Ocean Magic, but when they do, the gigantic wilds can really shake things up.
• The demo version lets you mess with all settings, so you can see everything the real-money game offers with zero pressure.

So yeah, it’s simple, but sometimes simple knocks it out.

King of Atlantis RTP & Volatility

King of Atlantis posts a theoretical Return to Player (RTP) of 95.00%, which is right around the industry average for slots. Some sources sneak the number up a hair to 96.14%, but most demo versions stick to 95%. In the grand scheme of high RTP slots, it’s normal, nothing wild, not stingy either.

The slot’s volatility is low, which in practical terms usually means you’ll see wins more often, just on the small side. Honestly, during several demo spins, I had plenty of little payouts with an occasional pop when the wild mechanic fired just right. Nothing felt “big money” but I rarely watched the credits just evaporate. “Low volatility slots” like this can be a relief if you’re tired of dead spins but, fair warning, the jaw-dropping wins are pretty rare.

RTP is just a long-term average; every spin is random. You can get hot in ten spins or see mostly duds for a while. Don’t try to time it. My experience, free spins popped less often than I hoped, but they did eventually show up, and when the gigantic wilds lined up, they felt satisfying even if the win wasn’t huge.

How to Win on King of Atlantis: Symbols & Payouts

You win by landing matching symbols from left to right across any of the 40 fixed paylines. The core mechanics? Get three or more matching symbols on a line, with the first one starting from the left. High-value symbols include Poseidon (wild), the trident bonus, rings, crowns, harps… with the lower values being gems and shells.

The Poseidon wild is where things get spicy. He lands stacked on reels 2 and 4 and can expand to create a 2×5 block if you use more wilds in your settings. More wilds mean a higher chance at big combos, but your spin cost increases. Trident symbols on reel 1 plus a wild block trigger the free spins bonus, which can sometimes pick up the pace (but don’t expect this every five minutes).

No gamble feature here. My personal record in the demo: managed a wild block for a decent line hit, but didn’t see any “all reels wild” insanity. Bonus wasn’t easy to trigger, maybe once every 100+ spins. If you’re interested in advanced feature games, try out some bonus buy slots where you can actually pay to skip straight to the bonus, which you can’t do here.

King of Atlantis Jackpot

King of Atlantis doesn’t have a traditional jackpot or progressive prize, so don’t expect rolling numbers or jackpot meters. Instead, the maximum payout advertised hits a pretty big number if you land the game’s highest-value combos, especially with wilds maxed out. In numbers, the game’s top win is set at 25,000,000 credits, but let’s be real, it takes a miracle spin with the right wild settings to get anywhere close. There’s no gamble ladder or side bet jackpot features, just that simple “max potential” if everything lines up.

King of Atlantis Visuals & Design

IGT sticks with a bold, colorful look for King of Atlantis. The whole grid bobs against a cartoonish sea background with big, shiny symbols, lots of blues and golds. The Poseidon wild is hard to miss, giant, bearded, and a little bit dramatic in his art style. Animations are pretty smooth, but not flashy enough to distract you. It’s friendly on the eyes, and you’re never left squinting to see paylines or feature animations.

Soundwise, it’s about what you’d expect: bubbly underwater tones, some fanfare when you score a payout, but nothing to make you rush for headphones. It feels polished but simple. For UI, everything you need is on-screen, but you won’t find fancy menus or turbo buttons, just manual start and paytable access.

Play Responsibly

King of Atlantis at Gamesville is for entertainment only. You can spin as long as you want and no money is ever won, lost, or at stake here. The demo version eliminates all financial risk, and all spins are random, previous results have no impact on future spins. Any “learnings” or experiences here don’t transfer to real casino play, and the demo doesn’t prepare you for real bets or change the actual risk if you do play for money. If you ever consider gambling at a casino, do it legally and always play responsibly.

Gamesville Verdict: Is King of Atlantis a Good Slot Machine?

There’s a lot to like about King of Atlantis if you’re into steady-action slots and enjoy tweaking wild settings. The gigantic wilds are actually fun to play with, especially as you experiment with different amounts per spin. On the other hand, if you love slots packed with multipliers, bonus buys, or cascading reels, King of Atlantis can feel a little sparse.

IGT’s solid reputation doesn’t hurt either, they make a lot of dependable games (check out our IGT slots list for more proof there). This game is not for people chasing megabucks or big win slots; it’s for folks happy to catch a steady stream of little wins with the occasional big splash if Poseidon smiles your way. Graphics stay sharp even on mobile.

For alternatives, if you had fun here, you might also want to check:

• Ocean Magic: Another IGT title, also in the underwater zone, but with different bonus mechanics and stacked wilds.
• Cash Eruption: More “modern IGT,” with cash-on-reels features and respin bonuses that give a totally different pace.
• Queen of Atlantis by Pragmatic Play, which is a little more high-strung in volatility and bonus potential but shares that Atlantis vibe, and offers more bonus options.

Most importantly, you get to spin here with zero worries about money or legalities. If you eventually get curious about regulated online play, don’t forget to check out legit sweepstakes casinos, which always offer no-purchase options and ways to try even more slot machines for free.

Similar Slots Like King of Atlantis

If King of Atlantis ticked your boxes, I’d point you straight to Ocean Magic for its sea theme, expanding wilds, and slightly juicier free spins, kind of a “cousin” to this game by the same developer, IGT. Prefer bigger, punchier bonuses? Cash Eruption leans into hold & respin mechanics, but with that IGT polish and easy-to-understand paytable.

If what you’re after is more of that Atlantis theme, Pragmatic Play’s Queen of Atlantis fits the bill with wild-rich bonus rounds that can surprise you on any spin. There are dozens of other online slots in this vein, but these three are a solid starting point for anyone getting their fins wet.
