A brand new video slot game by Thunderspin is called Monster Sushi. It’s a medium-risk slot machine with five reels and ten paylines. The RTP is 95.6%. Wilds, Scatters, Free Games, and Multipliers all center around the game’s culinary theme.

Monster Sushi

Trying your luck at slot machines with a culinary theme is like traveling the world searching for delicious treats. Fresh sushi prepared by a renowned chef? What could be better than that? You won’t find any sushi here that resembles the offerings at a restaurant. The sushi used in this dish is both armed and dangerous.

Graphic, Theme, and Soundtrack

The background of this slot is a muted grey and brown color scheme. The background of the slate-gray reels is made up of Japanese mountains and tea houses that move by on the screen. The muted color scheme creates an eye-catching display by allowing the brighter colors used for the game symbols to stand out. The unhappiness of the sushi being served as food results in some very intriguing game symbols!

The gameplay is accompanied by an authentic Japanese soundtrack. If you don’t like it, you can easily turn it off from the game’s main menu settings. It gives the game some extra atmosphere.

Monster Sushi Bonus Features

This slot isn’t known for having many bonus features, instead, it’s quite simpler with it, and has only a Free Spins bonus round.

Let’s have a closer look at how Free Spins operate:

Monster Sushi Free Spins

Regardless of how entertaining the base game is, the bonus features of an online slot keep players returning for more. The slot’s wild symbol is a strange jelly skull. It cannot produce cash payouts independently because it needs to be listed on the paytable. However, aside from the Scatter, it can replace all other game symbols, ensuring you always win.

The Bonus Scatter is a group of tiny faces wrapped in a sushi roll. Only two symbols must appear anywhere on the reels to activate the Free Spins bonus round. Furthermore, the multiplier and number of free spins increase as you land more scatters.

Bonus Scatters appear only in the first game. The number you spin determines the following bonus awards:

  • Two Scatters activate eight free spins with a 2x multiplier.
  • Three Scatters activate 11 free spins with a 3x multiplier.
  • Four Scatter symbols activate 14 free spins with a 4x multiplier.
  • Five Scatters will award you 17 free spins with a 5x multiplier.

RTP and Volatility

This slot machine has an RTP of 95.6% on the low side. The payouts are reasonable and low, so it’s a good idea to play the game for free first to get a feel for how it works. If you like to play this game, we have a lot of free Thunderspin slots for you to try.

Bet Sizes and Paytable

Even though there are strange life forms here, the game is still good. There are ten paylines, and all of them pay from left to right. The bet levels range from 1 to 10, and the coin values range from 0.01 to 1.

Through the settings menu, players can also change the quick spin, sound, and image settings; autoplay can be turned on for up to 500 spins with optional win and loss limits.

Monster Sushi Symbols and Payouts

Various horribly distorted sushi and sashimi, including irate octopus, salmon, tuna, and angler fish, are used as game symbols. The bonus symbol, which unlocks free spins, is a plastic bag of sliced, sentient sushi, while the game’s unsettling wild is a brain made of noodles. Lower-value symbols include the ranks of aces through jacks on a deck of cards.

To win money prizes multiples of your payline bet, line up three, four, or five symbols on one of the game’s ten paylines. The symbols payout are sorted as low-paying and high-paying:

Low-paying Symbols

  • J – 3x, 5x, 10x
  • Q – 5x, 10x, 25x
  • A – 10x, 20x, 30x
  • K – 10x, 15x, 35x

High-paying Symbols

  • Fish roll – 15x, 30x, 100x
  • Sushi – 20x, 50x, 200x
  • Octopus – 25x, 100x, 500x
  • Angler Fish – 100x, 500x, 1500x
