Manta Mayhem Slot RTP, Details, and Wager Limits
The setup in the Manta Mayhem slot is nice and simple. The action plays out on a 5-reel, 3-row, 20-payline machine. Create winning combinations by landing 3, 4 or 5 matching symbols or wilds from left to right in one of those 20 paylines, starting from reel 1. You’ll find this extremely popular format in many of the best online slot games.
There are stake ranges for all players, whether your bankroll is of tiddler or whale proportions. You can play from between 10p and £60 per spin (£5 max in the UK). Autoplay and quickspin modes are available in some territories, but not in the United Kingdom.
Like most Play’n GO online slots, the Manta Mayhem RTP is a mid-ranking 96.2%. That’s slightly better than average but not quite up with the best payout slots. These tropical waters can be rather choppy for your bankroll as the volatility is very high. The Manta Mayhem max win is 9,000x. That’s more than what’s on offer in many recent releases.
The biggest catch of coins I landed when playing the Manta Mayhem demo slot was 153x. I netted this haul in the free spins, with the multipliers providing a big helping hand. As you’ll discover below, the boosters are the key to success during the feature round.
If you like to test games without risking your bankroll, we have a huge collection of free casino slots available.
Manta Mayhem Theme—Dive into Tropical Waters
The visuals in the Manta Mayhem slot game are rather lovely. Watching over proceedings is a jolly manta ray who crackles with energy.
Tropical turquoise waters, a sandy seabed and assorted aquatic creatures form the backdrop to the reels. There, you’ll find seaweed-style A to 10 royal symbols and four higher-paying sea creatures. The visuals are bright and colourful, and everything is really easy to identify.
The soundtrack has a really jaunty feel. Combined with the bubbling sounds of the ocean, it makes for a terrific atmosphere. This is another sensual treat from Play’n GO that compares well with the best new slots.
Here’s what the paytable looks like if you’re playing at UK online casinos.
| Symbols | Payout/Info |
|---|---|
 10 | 3, 4 or 5 = 0.3, 0.4 or 0.8x the stake |
 J | 3, 4 or 5 = 0.3, 0.5 or 1x the stake |
 Q | 3, 4 or 5 = 0.4, 0.7 or 1.5x the stake |
 K | 3, 4 or 5 = 0.5, 1 or 2x the stake |
 A | 3, 4 or 5 = 0.6, 1.2 or 2.5x the stake |
 Shrimp | 3, 4 or 5 = 0.8, 1.5 or 4x the stake |
 Octopus | 3, 4 or 5 = 1, 2 or 5x the stake |
 Purple Fish | 3, 4 or 5 = 1.5, 3 or 6x the stake |
 Orange Fish | 3, 4 or 5 = 2.5, 5 or 10x the stake |
 Wild | 3, 4 or 5 = 4, 7.5 or 20x the stake |
 Pearl Scatter | Can trigger Clam the Prize Bonus |
Manta Mayhem Mobile Slot
I had a slight issue when playing the game on my tablet as the bottom of the screen, complete with the control buttons, was partially cut off. Portrait mode was perfect, though. The vibrant visuals are just as lush when playing at a mobile casino as on a desktop computer. The game is easy to play on small-screen devices.
Manta Mayhem Bonus Features
The highlight of the Manta Mayhem bonus features is the free spins feature. Boosting your chances here is a collection of modifiers that deliver wild and multiplier extras.
Clam the Prize for Free Spins
Each time a clam symbol lands, its pearl is swallowed by the manta above the reels. This can randomly trigger the Free Spins feature.
Once triggered, pick one of the clams. You’ll then receive 6 free spins with 3 boosters, 8 free spins with 4 boosters or 10 free spins with 5 boosters.
Before the free spins start, you’ll pick from a selection of pearls to reveal what boosters are in play during the free spins. They include:
- 2–4 extra spins
- High-paying symbols become stacked
- Sticky wilds are on reel 2
- Sticky wilds are on reel 3
- Sticky wilds are on reel 4
- 1 high-paying symbol transforms into a wild
- 2 or 3 random wilds are added on each spin
- All wins multiplied by 2x, 5x or 10x
With a minimum of three boosters active on each spin, there’s plenty to look out for during the free spins feature.
Go Ultra (Not Available to UK Players)
Players in some territories can increase their stake by 50% on each spin and activate Go Ultra mode. In return for that extra investment, the number of free spins and boosters increases by 1 when you trigger the bonus round. This bonus buy isn’t on offer to players at UK Manta Mayhem casinos.
Manta Mayhem Verdict: Simple but Entertaining Underwater Action
The appetite for slots with an ocean setting shows no signs of ebbing away. Manta Mayhem is a perfectly playable example of this exceedingly popular genre. Visually, it’s a delight. The rather jolly manta at the top of the screen is a dominating presence throughout.
Features-wise, it’s not the most original selection. A free spins round with multiple modifiers is usually a solid package, and that’s precisely what you’ll find here. Land the higher number of boosters, and they can combine to spectacular effect. As you might expect, there’s a bit of a sting in this manta’s tail, and that’s the high volatility, which won’t be for everyone.
Overall, though, I found plenty to like in Manta Mayhem. It’s another typically accomplished release from the Play’N GO stable and one to consider if you like the fishy theme.
