  • Are you a fan of video and arcade games from the 1980s?
  • Are you up for trying something cool and different?
  • Are you ok with riskier slots in return for a higher max win potential?

If you answered yes to at least one of the above questions, then Sumo Sumo could be just what you’re looking for.

Game studio ELK Studios keeps delivering quality slots, and Sumo Sumo is another proof of their excellence and where they are heading.

Get yourself ready for some exciting features you probably haven’t encountered earlier.


Sumo Sumo RTP

This is the most (and maybe only) disappointing point about Sumo Sumo, as the highest RTP version of the slot averages a 94% payout.

We have reported earlier about ELK Studios lowering their RTPs to 94%, and unfortunately, Sumo Sumo is yet another game that can be added to that list.

We believe it’s more about greed than laziness that ELK released only one 94% RTP version of the game instead of several versions with variable RTPs.

It´s a real shame, as the game is otherwise of the highest entertainment value.

What is the best Sumo Sumo casino?

If the 94% RTP setting doesn’t bother you too much and you are willing to give Sumo Sumo a go anyway, then you can choose one of the trusted online casinos here that offer the slot to their players.

To add some value to the proposition, you can choose a casino where you don´t have an account yet and start playing Sumo Sumo with an increased balance, as you are then entitled to a welcome offer (in the cases where the casino offers one).

Remember to look through any wagering requirements on the bonus before you start playing.

Gameplay and features

Sumo Sumo is a highly volatile slot played on a 5 reel and 5 rows game panel with 259 ways to win.

The base game offers some fun entertainment through the Wild Sumo Stacks and growing multipliers, but it’s within the Speedboat bonus and Free Spins that things really can take off.

Available Features:

  • Wild Sumo Stacks = Any sumo symbols nearby each other may jump on top of one another and create Wild Sumo Stacks.

The more sumos on top of each other, the higher the multiplier. The Wild stacks create a respin, and the sumos become walking wilds.

When no more wins happen or no new additions to the Sumo Stacks occur, the respins stop, and the next spin starts from scratch with the stacks gone.

  • Speedboat Bonus Game = 3 bonus symbols trigger the Speedboat Bonus Game.

This is played on a 5×5 grid starting with 3 spins which resets each time new symbols are collected.

The symbols consist of multipliers that can grow through different modifiers.

  • Free Spins = 2 FS symbols trigger 6 Free Spins.

During this bonus game, the Wild Sumo Stacks don’t disappear between spins where nothing happens. 

Sumo Sumo Bonus Buy

In countries where available, you can choose between a few different bonus bets.

  • 10x bet: A spin with a guaranteed brawl where two sumos fight and increase the multiplier.
  • 50x bet: Speedboat Bonus.
  • 100x bet: Speedboat Bonus with added potential.
  • 500x bet: Free Spins

What is the maximum win on Sumo Sumo?

Sumo Sumo is one of ELK Studio’s highest-paying slots; you can win up to 25,000x your bet size.

Remember that the game is highly volatile since the max win is that high.

So while there is enormous win potential in the bonus games, they can sometimes pay poorly or nothing.

Always play responsibly.

CasinoWizard’s verdict: 3 out of 5 stars

This was a lot of fun, and ELK Studios provided us with many pleasantly surprising elements in Sumo Sumo.

The 1980s arcade game flashbacks are there, especially in the Speedboat Bonus with the graphics and soundtrack.

Wild Sumo Stacks that can become colossal walking wilds with increasing multipliers were another fun addition.

These can become valuable, especially in the Free Spins, where they don’t disappear between non-winning spins.

If you get lucky and create several Wild Sumo Stacks with high multipliers all over the screen, then the significant win potential is there during the coming spins.

Sumo Sumo is a super cool and entertaining slot that online casino players worldwide will enjoy.

The only real shame is the game studio’s recent commitment to continue releasing slots with a lower 94% RTP.
