Symbols in Sumo belong to several different categories. The low-value ones consist of card ranks with 0.2x to 4x the stake. High-value symbols are dishes like Rice, Ramen, and Blue with Red Sumo Fighters. They provide rewards up to 8x the stake. The most valuable symbol is Tori, which has 2x, 4.8x, and 10x the bet.

In Sumo you can land the following special symbols:

  • The referee is a Wild that replaces missing symbols in combinations. During free spins, it lands with 2x, 3x, and 5x multipliers
  • Fuji is a Scatter symbol that can trigger the Free Spins feature.

Overall Rating

7.4

Sumo from KA Gaming is quite a small slot. The visual style is nice and has excellent details. However, there is no music in the background. So, to feel the atmosphere you need to keep the reels spinning. Sumo is not an innovative online slot. It has just several features. But they allow reaching 3,060x the stake. Free Spins can become almost endless. With Scatters you can pile up lots of bonus rounds. And Wilds with multipliers help to get nice winnings.

Winning: €4
Multiplier: x8
KA Gaming is one of the leading developers of Asian-themed slots, so it’s not surprising to see a game about Sumo in the provider’s portfolio.
The slot has pretty funny design and a simple gameplay. Basically, the only feature of the game is free spins with wild multipliers. The slot is a bit of up and down. You can easily go on 200 spins without a single 10x win and freebies. And getting a decent X can take some time and there are no guarantees that your big win will cover previous losses.

OMG, what a generous slot. It has given me 8 free spins as i collected the 3 scattered cards in 1 round. Then it just did not stop giving extra free spins and my winnings kept increasing more and more. It has reached 160x . I have the feeling if i continued playing it was just gonna keep giving FS's :) however, when u catch a nice win I always prefer to leave it short and sweet. I would highly recommend this slot to everyone. It's easy to play and easy to win + even the volatility is high.
