Game Overview
Manta Mayhem is a Play’n GO pokie released on 14 May 2026. The game uses a 5x3 layout, 20 fixed paylines and left-to-right wins from the first reel. The version checked has a $0.10 to $60 bet range, a 9,000x max win and a top RTP setting of 96.20%, with lower RTP versions possible by casino. Volatility is listed as high, so the best parts sit around Free Spins rather than plain base-game hits. Pearl Scatters can trigger Claim the Prize, which awards 6, 8 or 10 Free Spins with 3, 4 or 5 boosters. With GO Ultra active, those results increase to 7, 9 or 11 Free Spins with 4, 5 or 6 boosters.
Game Features & Mechanics
-
Fixed Paylines
The game uses 20 paylines across 5 reels and 3 rows. All wins pay left to right on adjacent reels.
-
Pearl Trigger
Pearls can land once per reel in the base game. They are collected by the Manta Ray and can trigger Claim the Prize.
-
Free Spins
Claim the Prize awards 6, 8 or 10 Free Spins with 3, 4 or 5 boosters. Free Spins cannot retrigger.
-
GO Ultra
GO Ultra adds 50% to the total bet. If Free Spins trigger while active, both Free Spins and boosters increase by 1.
Technical Specifications
-
Volatility Level
Manta Mayhem is high volatility. You should expect more pressure around Pearl collection, Claim the Prize and boosted Free Spins than base spins.
-
RTP Explained
The top RTP setting is 96.20%. Lower RTP versions may exist, so the in-game rules should be checked before real-money play.
-
Bet Range
The reviewed version runs from $0.10 to $60 per spin. GO Ultra increases the total bet by another 50% when switched on.
Paytable & Symbol Values
The regular paytable uses four high-paying sea creatures and five lower symbols. The orange fish is the strongest regular symbol, paying 10x for five, 5x for four and 2.5x for three. The purple eel follows with 6x, 3x and 1.5x. The blue squid pays 5x, 2x and 1x, while the green shrimp pays 4x, 1.5x and 0.8x. The lower symbols are A, K, Q, J and 10. A pays 2.5x, 1.2x and 0.6x. K pays 2x, 1x and 0.5x. Q pays 1.5x, 0.7x and 0.4x. J pays 1x, 0.5x and 0.3x, while 10 pays 0.8x, 0.4x and 0.3x.
Special Symbols
Wild
The Wild substitutes for all symbols except Scatters. It also pays 20x for five, 7.5x for four and 4x for three.
Pearl Scatter
The Pearl appears in the base game only and can land once per reel. Collected Pearls may randomly trigger Claim the Prize.
Sticky Wild
Sticky Wilds appear only in Free Spins as boosters. They may land on reel 2, reel 3, reel 4 or in combination.
HP Wild
HP Wilds appear only during Free Spins when awarded as a booster. One high-paying symbol type is randomly chosen and pays like the Wild.
Free Spins Booster
Free Spin Boosters are picked before Free Spins. They can add spins, stack premium symbols, add Wilds, create Sticky Wilds or multiply wins.
Win Multiplier Booster
One booster multiplies all Free Spins wins by x2, x5 or x10. The revealed multiplier applies for the entire feature.
Random Wilds Booster
The Random Wilds booster adds 2 or 3 Wilds to the reels during Free Spins, giving extra help without changing the payline setup.
HP Symbol Wild Booster
This booster turns 1 high-paying symbol type into a Wild during Free Spins. The chosen symbol is random for that awarded feature.
Graphics, Animations & Sound Design
-
Graphics
Manta Mayhem uses a bright underwater setup with a large Manta Ray above the reels and a purple-framed 5x3 grid below it. The sea creatures are easy to separate by colour, and the Pearl symbol stands out clearly when it lands in the base game.
-
Animations
The most useful animation is the Pearl collection, because it shows the Manta Ray taking the symbol from the reels. Free Spins also change the screen enough to feel different, especially when Sticky Wilds, stacked high-paying symbols or the x2, x5 or x10 win multiplier booster appears.
-
Sound Design
The audio stays in a light ocean style, with bigger effects around Pearl collection, Claim the Prize and Free Spin boosters. It does not need to explain the game, because the important steps are shown directly through the Pearl, clam picks and booster icons.
-
Visual Feel & Interactivity
The 20-payline layout is simple to read, so the game does not feel crowded in the base round. The interactive part comes before Free Spins, when Claim the Prize asks you to pick a clam and reveals the spin and booster package.
Game Gallery
Manta Mayhem on Mobile Devices and Other Platforms
Manta Mayhem works neatly on mobile because the base game uses only 5 reels, 3 rows and 20 fixed paylines. The screen is not overloaded, and the main trigger symbol is easy to spot because the Pearl appears large and bright in the centre of the reels. The GO Ultra switch also sits outside the main grid, so it does not block the action. Free Spins are slightly busier because boosters can add Sticky Wilds, stacked high-paying symbols, HP Wilds, random Wilds or a win multiplier. Phone play is comfortable, but tablet and desktop make the Claim the Prize stage clearer, especially when you want to read the booster icons before the feature begins.
-
Android
Android works well for regular spins because the 5x3 grid is compact. Landscape view helps when Free Spin boosters start adding more effects.
-
iOS
iOS is comfortable for short sessions. The Pearl, Wild and GO Ultra switch stay clear, even on smaller recent iPhone screens.
-
Tablet
Tablet gives the cleanest mobile balance. The clam pick screen, boosters and Sticky Wild positions are easier to follow without zooming in.
-
Desktop
Desktop is best for longer sessions. It gives more room for the payline grid, Manta Ray collection and Free Spins booster results.
Optimal Gameplay Tips
-
Use Stable Connection
EssentialPearl collection can lead into Claim the Prize, then into Free Spins. A stable connection helps the full chain play out cleanly.
-
Landscape Mode Recommended
RecommendedLandscape gives Manta Mayhem reels and GO Ultra switch more space. It is especially useful when boosters place Sticky Wilds on reels 2, 3 or 4.
-
Audio Settings
OptionalThe game is easy to follow visually. Set the audio where it feels natural, because Pearl collection and booster results are shown on-screen.
-
Full Screen Mode
RecommendedFull screen helps during Free Spins, where Sticky Wilds, HP Wilds, stacked symbols and win multipliers can all affect the same feature.

About Play'n GO — The Developer Behind the Game
Play’n GO is a major online casino game developer with a broad slot portfolio built across fantasy, adventure, mythology, animals, music and light cartoon themes. The studio often keeps the base rules easy to understand, then puts the more detailed action inside triggered features. Manta Mayhem follows that idea closely. The 20-payline base game is simple, but the Pearl collection and Claim the Prize sequence decide how much the Free Spins round can change.
The provider is also known for mobile-first design, which matters here because Manta Mayhem has several feature icons that need to remain readable on phone screens. The GO Ultra switch is another Play’n GO-style add-on, giving players a paid enhancement rather than a direct Bonus Buy. In this case, it increases the feature by 1 Free Spin and 1 booster only when Free Spins trigger while GO Ultra is active.
-
Broad Theme Range
The studio uses many themes, from mythology to ocean cartoons, but usually keeps symbol shapes and colours easy to separate.
-
Mobile Game Design
Play’n GO usually keeps controls clear on phones, with simple spin buttons, readable symbols and feature screens that scale well.
-
Bonus-Led Structure
Many Play’n GO slots keep the base game simple, then add more value through Free Spins, Wild features or pick stages.
Final Verdict
Why It’s Worth Playing
- The base game is easy to read, with 5 reels, 3 rows and 20 fixed paylines
- Pearl Scatters can open Claim the Prize, where clams reveal 6, 8 or 10 Free Spins
- Free Spins become more varied through 3, 4 or 5 boosters, depending on the awarded clam result
- GO Ultra adds 1 Free Spin and 1 booster, but only when the feature triggers while active
- The booster set includes Sticky Wilds, HP Wilds, stacked premiums, random Wilds and x2, x5 or x10 win multipliers
Things to Consider
- High volatility means the strongest play is tied to Pearl triggers and boosted Free Spins, not steady base hits
- GO Ultra raises the total bet by 50%, so it changes the cost of every active spin
- Free Spins cannot be retriggered, even when boosters add extra Wilds, multipliers or more Free Spins
Overall Rating
8.6
Bottom Line
Manta Mayhem works best if you like simple base-game structure with a more changeable bonus round. The 5x3 grid and 20 paylines are easy to follow, while the Pearl trigger gives the game its main lift. Claim the Prize is the key moment, because it decides whether you get 6, 8 or 10 Free Spins and 3, 4 or 5 boosters. GO Ultra can improve that package to 7, 9 or 11 spins with one extra booster, but the 50% extra cost matters. We like the clear booster variety, especially Sticky Wilds and the x10 win multiplier.
