Information

Payline wins are awarded on the number of paylines selected, according to the paytable and game rules. Wins on multiple paylines in a single game round will be combined. All wins from features (such as Free Spins), Bonus Rounds, and/or Specials (if applicable) are also added to payline wins. All winning combinations are paid at the end of a game round. Free Spin features are played with the same bet and number of lines selected as the game round that triggered the feature, unless otherwise stated. The bet cannot be changed during an ongoing game round. See the game rules for details. All wins are paid from left to right, starting with the leftmost reel. Symbol wins pay for any winning payline combination without gaps. Only the highest win per active payline will be awarded.

Rules of the game

MANTA MAYHEM is a 5 reel game with 20 fixed paylines.

This game features special symbols: SCATTER, WILD, and SPECIAL WILDS. The Pearl symbol is a SCATTER symbol that can appear once per reel only during the Base Game and is collected by the Manta Ray on the reels. Collecting Pearl symbols can trigger the CLAM THE PRIZE feature. The number of Pearl symbols collected does not affect the probability of triggering the CLAM THE PRIZE feature. The WILD symbol substitutes for all symbols except the SCATTER symbol.

SPECIAL WILDS

There are two SPECIAL WILD symbols. The STICKY WILD symbol can appear on reels 2, 3, or 4, or in combinations of these reels, depending on the FREE SPIN BOOSTER awarded, and remains in position until the FREE SPINS feature ends. The HP WILD symbols consist of four types, but only one is randomly chosen to appear during the FREE SPINS feature, and they pay the same as the WILD. The SPECIAL WILD symbols substitute for all symbols except the SCATTER symbol and appear only during the FREE SPINS feature as a FREE SPIN BOOSTER.

Collecting pearl symbols can trigger the CLAM THE PRIZE feature. In this feature, you choose a clam to determine the number of FREE SPINS and FREE SPIN BOOSTERS awarded. The selected clam can reveal 6 FREE SPINS with 3 FREE SPIN BOOSTERS, 8 FREE SPINS with 4 FREE SPIN BOOSTERS, or 10 FREE SPINS with 5 FREE SPIN BOOSTERS. The clam's appearance does not represent actual odds.

After the CLAM THE PRIZE feature, a number of FREE SPINS and FREE SPIN BOOSTERS are awarded. Before the FREE SPINS feature begins, choose Pearls to win FREE SPIN BOOSTERS that enhance the feature. The revealed FREE SPIN BOOSTERS remain active for the entire duration of the FREE SPINS feature. The FREE SPINS feature cannot be reactivated.

FREE SPIN BOOSTERS

Eight Free Spin Boosters are available and hidden behind the Pearls. These Free Spin Boosters include: two or four additional Free Spins; stacked high-paying symbols on the reels; Sticky Wild symbols on reel 2; Sticky Wild symbols on reel 3; Sticky Wild symbols on reel 4; one high-paying symbol transformed into a Wild symbol; two or three Random Wild symbols on the reels; and all wins are multiplied by x2, x5, or x10. The number of Pearls that can be selected corresponds to the number of Free Spin Boosters awarded in the Clam the Prize feature. The presentation of the Pearls does not represent actual odds.

The average player's return percentage is 94.20%. The RTP is achieved through participation.

Bets are selected using the bet buttons. Press the "plus" and "minus" buttons to adjust the bet level. To start the round, press SPIN. When the reels stop, the displayed symbols will determine your win according to the paytable.

1. The number of FREE SPINS and FREE SPIN BOOSTERS is increased by 1 each.

The benefits only apply to the feature when it is activated in a round while GO Ultra is active.

Actions

  • Auto Play - You can disable/enable the Auto Play feature in the menu. In Auto Play mode, several consecutive rounds of play will automatically start with your current betting settings. Auto Play mode is automatically deactivated based on your settings or if your balance is too low.

The selected reduced total bet will be the highest possible bet and will be lower than the bet size selected when the automatic spins were started. The bet will only be reduced and will not return to its original amount after any winnings that would allow you to continue with the initial bet size.
