Pros
  • Free spins round.
  • Stacked sumo multiplier wilds.
  • Speedboat bonus round.
Cons
  • Low 94% variance.
  • No win and loss limits in autoplay.

It is a 5x5 slot with 259 ways to win. The RTP is 94% and the variance is medium to high. Part fruit machine, partly themed around the Japanese sport of sumo wrestling, this slot has features including free spins, multiplier wild sumo stacks, walking wilds, sticky wilds and the speedboat bonus.

Introduction

ELK Studios decided to go down and dirty in Sumo Sumo. An exciting 5x5 layout with an impressive 259 ways to win is situated in a dirty, rubbish-strewn alley where two sumo wrestlers go toe to toe. Watching these street brawls is a chance to win one of several exciting bonuses in an innovative, highly original game that will appeal to action movie fans.

Theme, Graphics & Soundtrack

Take one classic online slot theme: the fruit machine. Take one a little rarer: sumo wrestling. It’s not often we cover both in the same slot review, but in Sumo Sumo, these two traditional themes sit comfortably side by side, all to a poundingly modern electronic soundtrack.

Well, calling it a classic fruit machine may be pushing it a bit. Each traditionally rounded fruit has been cut into an unusual blocky square shape. And while sumo may be Japan’s most iconic national sport, this version has been taken out of its highly ritualised setting and put out in a back alley like its wrestlers are two streetfighters. When they become animated, they brawl across the reels.

That’s even before you trigger the speedboat bonus on the waterfront. When was the last time you saw a sumo wrestler in a speedboat?

Sumo Sumo RTP and Variance

If we have one single major criticism of the Sumo Sumo online slot, it’s the RTP. If you’ve read any slot review before, you probably know that our recommended figure is 96%. Sumo Sumo is only at 94%. It could only be worse if it had an even lower variation, like in the Little Bighorn slot.

The variance is better, at a medium to high level, although some players still may find that nerve-wracking. The higher the variance, the rarer the wins. Other players prefer this, however, because it can mean higher single wins.

How to Play Sumo Sumo

It might be an unusual format, but the basics are those of any ELK Studios slot:

  1. You’ll be offered the chance to switch the sound on or off when loading.
  2. Once the game’s open, you’ll see the menu button in the top left. It will take you to the paytable, from where you can navigate to settings, rules and promotions.
  3. In settings, you’ll find sound effects and music separately. You can also activate quick play and show in coins.
  4. Back on the main screen, the bet button is in the bottom left. Bet to your limits.
  5. The top right hosts autoplay, with up to 100 automatic spins. On the bottom right is the spin button to turn the reels once.
  6. However you play, enjoy, but don’t forget to be responsible. Play as a free slot and to minimize the risk.

When the fun stops, stop.

Sumo Sumo Bonus Features

What kind of slot review doesn’t cover bonus features?

Free Spins

It only takes 2 free spins symbols to trigger the free spins round. You start with 6 free spins but can retrigger. Stacked sumo symbols don’t disappear but stick around, sometimes growing and potentially bringing re-spins.

Sumo Stacks

Sumo wrestlers of the same colour stack on top of each other, acting as wilds and increasing their multiplier. More sumo wrestlers add free re-spins. Wrestlers can walk across the reels, and stacks of different colours will often get into brawls.

Speedboat Bonus

Find 3 bonus symbols and you can jump into your speedboat to collect multipliers from the water, even as you save lives. Here’s what you can collect as you sail across the harbour:

  • Wakeboarder: He’ll attach himself to your moving boat, and as long as he holds on, his values increase.
  • Swimmers: Pick them up from the water and win their cash value at the same time.
  • Ramp: Speedboat and wakeboarder values both increase when you do tricks with the ramp.
  • Harpoonist: Any symbol you haven’t collected will increase in value.
  • Turbo Harpoonist: When you collect symbols, they increase in value.

Sumo Sumo Review

Writing the Sumo Sumo slot review was a lot of fun, but not half as much fun as playing it. This is a very distinctive slot that plays with its theme in a way we haven’t really seen before. Best of all, it is absolutely packed with features. If you’re lucky enough to combine sticky, stacked sumo wrestlers with free spins, it makes for a potentially rewarding and visually exciting feast.

FAQs

What is the RTP of Sumo Sumo?

Easily the most disappointing aspect of the Sumo Sumo slot is the RTP. Only 94%? We’d expect a lot better from a modern developer like ELK Games. If you’re comparing a slot of 94% to a slot of 96%, which one are you going to choose? It’s the sort of thing that leads to people missing out on the fun of games like Sumo Sumo.

What is the variance of Sumo Sumo?

Sumo Sumo does have a medium to high variance, which is another reason you might like to play this free slot. Most players will probably be satisfied with the balance of medium variance, but medium to high adds an extra note of risk that may increase the thrills.

Does Sumo Sumo have any bonus features?

Broadly speaking, you can divide Sumo Sumo into three bonus features: free spins, stacked sumo symbols and the speedboat bonus. In the case of stacked symbols and the speedboat bonus, both come with a range of different features of their own, including multipliers, re-spins and cash values. Stacked sumo symbols become sticky during free spins.
