Sumo Sumo Slot Review

If there was any sport that could be described as larger than life, it would be sumo. The iconic Japanese combat sport is the most super-sized on the planet, and ELK Studios has leaned into this for the Sumo Sumo slot game. The slot comes suitably packed with great bonus features and some big winning potential. Let’s square up to it and see what it has to offer in this Sumo Sumo slot review.

Sumo Sumo Slot Game Design

Fans of old-school arcade beat-em-ups will enjoy the general design of the Sumo Sumo slot. The reels are set down a back alley in Japan, with graffiti and discarded fish lining the floors. The symbols on the reels are a mix of fruit and sumo wrestlers. The latter of these look as though they have been taken straight from something like Streets of Rage or Street Fighter, and there are also some sound effects in the game that reinforce this. On the whole, it’s a really fun design that does a good job of making itself stand out.

How to Play Sumo Sumo Slot

Sticking with the Sumo theme, ELK Studios has used a larger-than-normal game grid for the Sumo Sumo slot. The slot uses a 5x5 grid with 259 ways to win, which is more than you would find in your average top online slots.

The minimum a player can wager in the slot is $0.20, while the maximum sits at $100. This is a fairly solid betting range, which should please players with most budgets.

Playing Sumo Sumo Mobile Slot

Condensing a Sumo fighter is not an easy task, but ELK Studios has managed to do just that with the Sumo Sumo mobile slot. The game manages to maintain all of its quirks and its larger-than-life bonus features when it makes the move to the smaller screen. The slot is fully supported on both Android and iOS operating systems and can be found at a range of top new online slot sites.

Sumo Sumo Slot Bonus Features

There are several great online slot bonuses in the Sumo Sumo slot game to keep players involved in the action.

The first one that players will probably encounter is the Sumo Stacks and Respin Round. After a win, a Sumo Symbol can jump onto the back of another Sumo Symbol of the same color. This will then trigger a respin. The Stacked Sumo Symbol will become Wild and display a number equal to the number of Sumo fighters.

During the respin, the Stacked Sumo will move across the reels. They will go all the way to the right, and if they hit the rightmost reel, they will turn around. More Sumos can stack up during the respins. It is also possible to start another stack with the other colored Sumo. When there are no wins on one of the respins, then the round will stop, and the Wild will disappear.

If there are two Wild Stumo Stacks on the same row, they will start a brawl. The biggest of the two will win, and the multiplier of the loser will be multiplied by the winner and become one big stack.

One of the biggest bonuses in the slot is the Speedboat Bonus. This is launched when players land three of the Bonus Symbols. The slot then moves away from the back alley and down to the waterfront, with the action taking place on a different 5x5 set of reels.

This is a collection-type feature. Players are rewarded with three spins of the reels. A Sumo fighter on a boat is placed in the middle of the reels, and he will collect any symbols that land directly in his line of vision. Once he has collected one and moved to a new position, he will then move again if there are other symbols in his new line of vision.

There are four types of symbols that land during this game. The Swimmer Sumo is the most basic. It displays a value that will be added to the collection when it is rescued. The Wakeboarder Sumo is one of the most useful. It first adds its value to the speedboat, and then it tags along to the back of it. It will then collect its own values, being just one position behind the boat at all times.

The Ramp Symbol will display a multiplier value and will boost the value of the pot by this. Finally, there is the Harpoonist. This will help boost the values of any swimmers that have not yet been collected.

Finally, there is the Bonus Spins Round. This is launched when players land two Scatter Symbols. During the round, Wild Sumo Stacks stick to the reels until the end of the round.

In some countries, players may be able to buy their way into these bonus rounds for a pre-determined amount, thanks to the X-iter feature.

Sumo Sumo Slot RTP, Maximum Payout & Volatility

The maximum win in the Sumo Sumo slot game is suitably large. The biggest amount that can be won in the slot is 25,000x the player’s stake. The slot is considered highly volatile. The RTP in the game is slightly disappointing, sitting at just 94%.

Sumo Sumo Slot Summary

ELK Studios has delivered a brilliant online slot game with Sumo Sumo. Everything about this slot works. From its fun theme and design to its loaded bonus rounds, there is a lot for players to enjoy here. The only downside to the slot is a lower-than-average RTP, but a good maximum win and high volatility do counteract this. This is a slot we highly recommend taking for a spin at our recommended casino sites.
