Rules and Gameplay

Monster Sushi is an inventive slot game developed by ThunderSpin, featuring a unique theme where a pollution disaster has turned sea creatures into monstrous sushi. This game is played across 5 reels and 10 paylines, all of which pay from left to right. Players can adjust their bet level from 1 to 10 and the coin value from $0.01 to $1.00, allowing for a wide per-spin bet range of $0.10 to $100.00. The game also offers an Autoplay option for up to 500 spins, complete with win and loss limits for a tailored gaming experience.

Bonus Features

Monster Sushi offers several exciting bonus features designed to enhance gameplay and increase winning potential:

  • Free Spins: Triggered by landing three or more plastic bag bonus symbols. Players can receive between 8 to 17 free spins, with a win multiplier of 2x to 5x applied.
  • Win Multipliers: Every spin in the bonus play awards a cash prize of one bet multiplied by the win multiplier, irrespective of the outcome.

These features provide players with ample opportunities to score big wins, especially during the free spins round with generous multipliers.


The reels of Monster Sushi are adorned with an array of distorted, yet vibrant, sushi symbols, alongside traditional playing card values. Each symbol contributes to the game’s eerie yet captivating atmosphere:

  • Lower-Value Symbols: Playing card values Ace through Jack.
  • Higher-Value Symbols: Warped pieces of sushi and sashimi, including an irritated octopus, salmon, tuna, and angler fish.
  • Wild Symbol: A brain made of noodles, acting as a substitute for all other symbols except the bonus symbol.
  • Bonus Symbol: A plastic bag of sliced, sentient sushi, which triggers the free spins feature.


Payouts in Monster Sushi are determined by the symbol combinations landed on the reels. Here is a summary of potential winnings for various symbol matches:

Symbol 3x Match 4x Match 5x Match
J 3x 5x 10x
Q 5x 10x 25x
K 10x 15x 35x
A 10x 20x 50x
Octopus 25x 100x 500x

With its variety of symbols and the potential for high payouts, especially with the multipliers in the free spins round, players have the chance to win significant amounts.


Monster Sushi features 10 fixed paylines, meaning all paylines are active for every spin. This setup simplifies gameplay while maximizing the player’s chances of winning. Paylines pay from left to right, and only the highest win per line is paid.
