For reference, this slot is based on the Yokozuna rank which is the highest rank in sumo.

Symbols on the 5×5 grid include low value cherries, grapes, lemons and watermelons which are all cubes in shape and look futuristic. The 2 higher value symbols are represented by blue and red sumos.

Sumo Sumo Mobile
Released on the 6th of December 2022, Sumo Sumo was created using HTML5 technology. This means it has been optimised for mobile, tablet and desktop devices (i.e. laptop/PC). ELK Studios are a mobile-first provider so they cater to smartphone devices particularly. This includes iOS, Android and Windows operating systems.
Sumo Sumo Bonus Features
The Sumo Sumo slot game has 4 bonus features. Sumo symbols stack on top of each other to become a Walking Multiplier Wild. Wins involving multiple Walking Multiplier Wilds will see multiplier values multiply. With respins awarded, sumos can brawl and merge for bigger multipliers. There are free spins with Wild Sumo Stacks remaining in play but it’s all about the Speedboat Bonus feature which sees the Speedboat collect Wakeboarder and Swimmer Sumos as well as other special symbols for huge wins.
Sumo Stack Respin feature
Sumo symbols can appear stacked on top of each other. This triggers the Sumo Stack Respin feature with the stack of sumos becoming a Walking Multiplier Wild symbol. The number of stacked sumo symbols within a Wild Sumo Stack determines the multiplier value. For example, 3 stacked sumos will result in a 3x multiplier.
When you get a winning combination involving multiple Wild Sumo Stacks, the multipliers are applied multiplicatively to give you a final multiplier. Wild Sumo Stacks are created by winning on multiple sumo symbols within a payline. They then stack onto the last sumo symbol on the payline to create the Wild Sumo Stack.
Wild Sumo Stacks are also created by any win when multiple horizontally adjacent sumo symbols of the same type appear. A Wild Sumo Stack then awards a free respin with the Wild Sumo Stacks walking rightwards 1 reel during the respin. When the Wild Sumo Stack reaches the last reel (i.e. reel 5), it starts to walk leftwards 1 reel at a time. Any winning combination gives you a respin basically.
Furthermore, horizontally adjacent Wild Sumo Stacks of the same type merge during a respin. If opposite Wild Sumo Stacks are present on the same row, the rightmost Wild Sumo Stack runs at the leftmost Wild Sumo Stack and causes a brawl. The winner is the largest Wild Sumo Stack which then multiplies its value by the value of the losing Wild Sumo Stack. If both are equal in size, the winner is chosen randomly. The losing Wild Sumo Stack is then removed from the reels. Finally, Wild Sumo Stacks spin out on reel 1.
Speedboat Bonus feature
The Speedboat Bonus feature is triggered by landing 3 Hazard Bonus Scatters on reels 1, 3 and 5 simultaneously. 3 lives are then awarded. It takes place on a 5×5 slot with mini-reels and a collection mechanic. With a Street Fighter 2 style soundtrack, a Speedboat symbol is awarded at the beginning of the feature with an initial value.
Once in, unoccupied positions on the reels spin to reveal a symbol which then consumes a life. If a symbol lands in line of sight, north, south, east or west to the Speedboat symbol, lives are reset to 3. Then the Speedboat symbol travels across the reels to collect that symbol.
Now, collecting a symbol removes it from its position. Collections are also chained with the highest value route prioritised. Here’s what each of the special symbols offer:
|Speedboat||Moves in line of sight (north, south, east and/or west)|
|Swimmer Sumo||Speedboat adds the collected symbol value to its own|
|Wakeboarder Sumo||Speedboat adds collect symbol value to its own and activates the Wakeboarder counter. The Wakeboarder Sumo attaches to the back of the Speedboat with every new position the Wakeboarder Sumo travelling to increasing its value. Finally, the Wakeboarder counter increases in value per extra Wakeboarder Sumo collected.|
|Ramp||When collected, the Speedboat symbol value and Wakeboarder counter is multiplied by the value of the ramp symbol by performing tricks.|
|Harpoonist||Harpoonist or Turbo Harpoonist symbol values are added to the Speedboat symbol. They also increase the values of all uncollected Swimmer and Wakeboard Sumos by its own value on landing and for subsequent spins whilst uncollected.|
|Turbo Harpoonist||Turbo Harpoonist symbols additionally increase the values of all uncollected Swimmer and Wakeboarder Sumos by its own value per collection by the Speedboat Sumo.|
The feature only ends when all lives are lost and no collection is possible. Finally, the sum of the Speedboat value and the Wakeboarder counter value will determine your total win for the feature.
Free Spins feature
Landing 2 Free Spins Scatter symbols will trigger the Free Spins feature. With 6 free spins awarded, Wild Sumo Stacks stay in play between free spins. Additionally, they do not spin out on a loss or on reel 1. Finally, you can retrigger the feature to win an extra 6 free spins.
Players outside the UK can opt for the X-iter feature. With 5 different game modes costing between 5 and 500 x your total bet, here’s what each mode offers:
|Bonus Hunt||5 x bet||Increased chance of triggering the Speedboat Bonus or Free Spins features|
|Brawl Mode||10 x bet||Guaranteed brawl between Wild Sumo Stacks|
|Speedboat Bonus||50 x bet||Entry to Speedboat Bonus feature|
|Super Speedboat Bonus||100 x bet||Entry to Speedboat Bonus feature with all Harpoonists being Turbo|
|Free Spins||500 x bet||Entry to Free Spins feature|
Sumo Sumo Review Summary – brawl your way to huge wins
The Sumo Sumo slot is an interesting release by ELK Studios. With a unique theme and concept, the visuals are brilliant and is a welcome change from the likes of ancient Egypt or Norse mythology.
In terms of the gameplay, the Sumo Stack Respin feature sees Sumo symbols of the same type stack on top of each other when part of a win. The more sumos, the bigger the multiplier basically. If you get a win with multiple Wild Sumo Stacks, the multiplier values are multiplied. Respins are awarded until the Walking Multiplier Wilds disappear from reel 1 or isn’t part of a win.
The Free Spins feature offers more of the same with Wild Sumo Stacks not disappearing from the reels. It’s all about the Speedboat Bonus feature which is a brand new type of hold and spin game. The Speedboat symbol moves around the 5×5 grid to landing symbols in line of sight basically.
I quite like the Wakeboarder Sumo which sees its value added to the Speedboat and attach itself to add that value on each subsequent spin. It also increases the Wakeboarder counter. Ramp symbols are particularly important as the Speedboat value and Wakeboarder counter is multiplied by the ramp value. Then you have Harpoonist and Turbo Harpoonist symbols when see their values added to the Speedboat and increase the value of uncollected Swimmer and Wakeboarder Sumos.
A few spins in demo mode is definitely recommended but it’s about special symbols landing in line of sight to the Speedboat symbol. If you get lucky, wins of 25,000 x your total bet can be won. That said, I found the Free Spins feature to be the most lucrative feature as Wild Sumo Stacks remain on the reels throughout the whole feature.
If you want to head to Japan, Bushido Ways by Nolimit City comes with up to 12,288 ways to win and 30,000 x bet max wins. Another option is Sakura Fortune 2 from Play ‘n GO which offers 19,664.8 x bet top payouts.
