Play the Manta Mayhem online slot from Play’n Go, and enjoy an aquatic adventure with an impressive symbol collection mechanic. I found that winning sessions tended to be delivered via the free spins and boosters of the Clam The Prize feature. The visual and auditory entertainment provided by the giant mantra ray adds momentum to this fast-paced game and helps runs of dead spins and small wins feel less boring.

From the moment I loaded Manta Mayhem onto my mobile phone, my first impression was that Play’n Go did a great job of using a giant manta ray to add visual and auditory entertainment to this impressive aquatic-themed slot. From the moment you hear the manta’s excited squeal, your focus is on the game’s eponymous character. I found myself watching excitedly as he collected the pearls that could trigger the Clam The Prize Feature, and celebrated with him as he spun his fins to let me know the feature had triggered. This action deflects attention away from small wins and dead spins, and gives you the feeling that the bottom of the ocean is always alive, even when there’s little of any significance happening. The pacy soundtrack played its part in heightening my senses by mirroring the fast spin speed of the reels, so I advise you to play with the sound on at all times.
After 200 spins, it was clear that the gameplay, bets, features, and bonuses of Manta Mayhem revolved around the symbol collection performed by the giant manta ray. I had the fortune to trigger the Clam The Prize feature twice and experienced the type of downturn you might expect immediately afterwards.
If the pearl collection mechanic isn’t triggering the Clam The Prize feature every 100 spins or so, I think it might get a little tedious, but it didn’t feel that way during my sessions. I was happy that it combined with the bright and colorful aquatic setting to deflect my attention away from the dead spins and small wins I experienced while I was bonus chasing.
The chance to activate the Clam The Prize Feature is the main reason I’ll happily play Manta Mayhem again. The odd player may walk away with a top prize of 9,000x, but I was pleased with my wins of 47.10x and 125x, which resulted in two winning sessions and an overall win. The feature has great playability, as you first pick a clam to determine the number of free spins and boosters you get. You then pick pearls to randomly select your boosters.
The build-up is very exciting, and the boosters give the reels eye-catching momentum. It felt like something was happening on nearly every spin, as stacked high-paying symbols, sticky wilds, and high-paying symbols that transform into wilds all played their parts in creating winning combinations. The only boosters I didn’t experience were the 2x, 5x, and 10x multiplier symbols. I experienced a downturn of 29 coins after both feature wins, but this didn’t detract too much from my overall experience.
✅ The giant manta ray adds visual and auditory entertainment that deflects attention away from dead spins and small wins
✅ The fast pace of the soundtrack mirrors the spin speed of the reels
✅ The Clam The Prize Feature offers playability with its pick screens and variety through its many free spin booster options
Drawback – Adding the Ultra Bet does not increase your chances of activating features; it only gives you more free spins and boosters when you do.
If you’re a fan of aquatic-themed games looking for similar slots to Manta Mayhem, play Fish Trio™ or Big Bass Splash. Fish Trio features a coin mechanic, in which I enjoy collecting cash, multiplier, and boost coins. Big Bass Splash is a classic from Pragmatic Play in which collecting fish money symbols is just one of the features I regularly enjoy playing.
There are only three types of players that I can think of that won’t enjoy Manta Mayhem: beginners who may be overawed by the fast-paced action, those who prefer low-volatility affairs, and progressive jackpot pot hunters who may turn their noses up at the 9,000x top prize.
If you’re a player who likes to be visually and audially entertained as you chase a bonus, I believe you’ll enjoy the theatrics of the symbol collections, while the Clam The Prize feature offers great playability through its pick rounds, free spins, and boosters.
