Manta Mayhem

Manta Mayhem by Play’n GO is an online video slot that depicts a giant manta ray, set against a colorful ocean backdrop. The game pairs its underwater theme with a feature set built around Free Spins, special Wilds, and modifier rewards unlocked through a clam pick. This combination shapes the main action and drives the potential across each round.

Gameplay features and bonuses

Manta Mayhem runs on a 5-reel, 3-row grid with 20 fixed paylines. The game features a 96.2% RTP and a high volatility profile. Bets range from €0,10 to €60, and the maximum win has the potential to go up to 9,000x the bet.

Scatter (Pearl) Symbol: The Pearl acts as the Scatter symbol and may appear once per reel during the base game. Each Pearl adds to a collection tracked by the Manta Ray above the reels. Once enough Pearls accumulate, the Clam the Prize feature may activate. The total number of Pearls does not change the trigger odds.

Wild Symbol: The Wild substitutes for all regular symbols and helps complete winning combinations. It cannot replace the Scatter.

Special Wild Symbols: Special Wilds appear only during Free Spins and act as substitutes, just like the standard Wild. Two types exist: Sticky Wilds and HP Wilds. These symbols come into play through Free Spin upgrades.

• Sticky Wilds may land on reels 2, 3, or 4, based on the awarded booster. Once placed, they stay in position for the entire bonus round.
• HP Wilds include 4 possible variants, with 1 selected at random for each Free Spins round. Each version pays the same as a standard Wild and remains active throughout the feature.

Clam the Prize Feature: Pearl collection may unlock this feature. A selection screen appears, where 1 Clam reveals a reward. Possible outcomes include 6 Free Spins with 3 modifiers, 8 spins with 4 modifiers, or 10 spins with 5 modifiers. The display does not reflect actual odds.

Free Spins Feature: Free Spins begin after the Clam selection. Before the round starts, Pearls reveal modifiers that enhance the mechanic. These upgrades stay active for the full duration. No Retrigger option exists.

Free Spin Modifiers: Modifiers add extra effects to the bonus. Options include extra spins, stacked high-value symbols, Sticky Wilds on reels 2, 3, or 4, symbol-to-Wild conversion, random Wild placements, and win multipliers of 2x, 5x, or 10x. The number of upgraders matches the reward from the Clam selection. Their reveal does not indicate real probabilities.

GO Ultra Feature: When active, this option adds 1 extra Free Spin and 1 additional modifier on top of the reward from the clam pick and costs 1.5x the selected wager.

Design and Soundtrack

A large manta ray hovers above the reels, framed by a bright underwater scene filled with coral shapes and soft blue gradients. The grid uses a shell-like border, with symbols that feature sea creatures such as octopus, shrimp, and vivid fish, along with coral-styled 10-A classic figures. Colors stay bold and saturated, with smooth animations that highlight wins and feature triggers. The soundtrack leans toward light aquatic tones, paired with soft bubbles and playful effects that match the ocean theme without becoming distracting.

Players who enjoy this setting may also like titles such as Sea Fantasy by Pragmatic Play and Dolphin’s Pearl by Novomatic.

The Bottom Line

Manta Mayhem places its full potential on the Free Spins feature, which is triggered through Pearl collection and a Clam pick that sets the number of spins and modifiers. Each upgrade adds a modifier, such as Sticky Wilds on reels 2, 3, or 4, random Wild placements, symbol upgrades, or multipliers up to 10x. One HP Wild variant stays active for the entire round and adds extra value to wins. No Retrigger option exists, so results depend on the initial setup. The GO Ultra option grants an added spin and modifier, which can improve the outcome.
