Sumo Sumo Slot Overview

Sumo Sumo is a new casino slot from ELK Studios where we go to Japan and meet a bunch of Sumo wrestlers. Sumo wrestling is a Japanese religious ritual that has been around for over 1500 years, where two steady people wrestle and try to push their opponent out of the ring. It's a sport that at first glance may seem simple to do, where all you have to do is eat a lot and wrestle. But this sport in fact involves many rules both inside and outside the ring, where they have to wear special clothes, have a special hair style and for example are not allowed to drive cars, where the last one is due to a fatal car accident that occurred with a Sumo wrestler. One thing they have not set limits on, however, is their ability to drive speedboats and that is something they certainly take advantage of within this slot. It's a game that has a bunch of festive features that we can take advantage of, where we can scoop up wins of an incredible 25000X the bet. Let's visit this site and find out what you can expect to see during the spins.

Base game

Sumo Sumo is a video slot from ELK Studios that has 5 reels, 5 rows and 259 ways to win. One can choose between making a Min.bet of 0.20 and a Max.bet of 100. The game has been created with an RTP that is lower than the average, where we have an RTP of 94%. Sumo Sumo has a high volatility, where you can win up to 25000X the bet.

Within this Japanese gaming adventure, we have a couple of great features to help us in our quest for the big wins. The features are Wild Symbols, Wild Sumo Stack, Speedboat Bonus, Free Spins and X-iter.

Sumo Sumo Slot Information

The design of the game is a Sumo theme, where we go to Japan to meet these skilled wrestlers. In the background of the reels, we can see an alley with garbage and graffiti, where we will then move to other places during the game. You can play this slot on all the devices notepads, desktops and mobiles. You create a winning combination by landing 3 or more of the same symbol type on adjacent reels starting at the far left.

The lower paying symbols are square fruits showing cherries, grapes, lemon and watermelon. Landing 5 of the same symbol type pays between 0.5X to 2X the bet. The higher paying symbols consist of two Sumo wrestlers in the colors blue and red, where 5 of the same symbol type pays 5X and 10X the bet respectively. The game's wild symbol consists of a red W while the scatter symbol consists of the text Free Spins lit up by neon lights. During the spins you can also land a Speedboat Bonus symbol which is a warning triangle showing a person falling into the water from a dock. Let's find out what the features do.

Sumo Sumo Slot Features

What is the max win in the slot Sumo Sumo?

You can win up to 25000X the bet.

What features are available in the slot Sumo Sumo?

The features are Wild Symbols, Wild Sumo Stack, Speedboat Bonus, Free Spins and X-iter.

Wild Sumo Stack

Wild Symbols

The game's wild symbol helps to create more winning combinations by substituting for other symbols, except for the scatter and Speedboat Bonus symbols.

Wild Sumo Stack

During your spins you can land Sumo symbols stacked on each other’s, which then corresponds to a walking wild multiplier symbol. Its multiplier value corresponds to the number of Sumo symbols that are stacked, and you can stack these symbols by creating a winning line that includes several Sumo symbols. You can have multiple Wild Sumo Stacks and if you create a win where several of these are included, their values will be multiplied by each other before being applied to the win.

When you create a Wild Sumo Stack, you will receive a respin where they initially start moving at 1 step per respin towards reel 1. Once on reel 1, they will wander off the reel on any upcoming respin that is performed. Horizontally adjacent Sumo symbols will stack up with the Wild Sumo Stack and award a respin. A brawl occurs when you land two Wild Sumo Stacks on the same row, where the largest Sumo Stack will win the brawl. The winning Sumo Stack will have its multiplier increased by the amount that the losing Sumo Stack had. If the brawling Sumo Stacks have the same value, then the winner is randomly selected, and a brawl can change the direction of the Wild Sumo Stack.

Speedboat Bonus

Speedboat Bonus

If you land 3 Speedboat Bonus symbols, the Speedboat Bonus feature is activated. You are then greeted with 3 lives, and you are again playing with a 5X5 reel setup, where there now is a collection feature. You will have a Speedboat symbol placed out at the beginning with an X value, where the other positions will spin. Each time you spin you lose a life and if you land 1 or more symbols your lives will reset to 3 again.

The Speedboat will then go around and collect the values from the landed symbols, where you can land the following special symbols:

Swimmer Sumo Symbol = When you land this, the Speedboat will add the value of the Swimmer to itself.

Wakeboarder Sumo Symbol = The Speedboat adds the collected value from the Wakeboarder to itself and then activates a counter for the Wakeboarder Sumo Symbol. This Wakeboarder symbol will then be attached to the Speedboat and each position it is moved will increase its multiplier. The Wakeboarder symbol can stack up with several and it is the number of symbols that determines how much each moved position will increase its value by.

Ramp Symbol = This will multiply its value by both the Speedboats and the Wakeboards collected value.

Harpoonist Symbol = The Speedboat will add the value from the Harpoonist Symbols to itself. The Harpoonist will increase the value of all uncollected Swimmer and Wakeboarder symbols as long as it remains uncollected. You can also land a Turbo Harpoonist Symbol, and it will also increase the value of the Swimmers and Wakeboarders one last time when it finally becomes collected by the Speedboat.

This bonus game then ends when you either run out of lives or have no collection possibility presented. You will then receive the total amount that the Speedboat and the Wakeboarder have collected.

Free Spins

Free Spins

If you land 2 scatter symbols then the Free Spins feature is activated, where you are welcomed with 6 free spins. Within this bonus game, the Wild Sumo Stack will stay in place between the free spins, and they will not be removed from the reels on loss or when placed on reel 1. You can obtain 6 extra free spins by retriggering the bonus game.

X-iter

If you want to take advantage of the features right away, you can use the X-iter bonus buy option. You can then choose from the following options:

2X (Bonus Hunt) = This increases your chances of activating the Speedboat Bonus and Free Spins feature.

25X (Brawl Mode) = You are guaranteed to activate a Brawl between the Sumos.

100X (Speedboat Bonus) = You activate the normal Speedboat Bonus game.

250X (Super Speedboat Bonus) = You activate the super Speedboat Bonus game and every Harpoonist symbol is now Turbo Harpoonist symbols.

500X (Free Spins) = You activate the Free Spins feature.

Sumo Sumo Slot Conclusion

Within this slot we go outside the ring with some Sumos, where these Japanese wrestlers show a great passion for speedboats. A hobby that may have grown out of their ban on driving cars, which is something we only can speculate about, but something we can state is that they like action-packed moments. During the base and free spins, we can take part in some big brawls between the Sumos, which can act as Walking Multiplier wilds. Their multipliers can stack up to be really festive and thus help generate big wins. The moving wild multiplier is something we've seen within a couple of previous games from this game provider, where just like in Phoenix Graveyard, this game also can provide long lasting spins.

It's a game that has many entertaining moments, but it's clearly the Speedboat Bonus that's most memorable. There you get to take part in a respins feature with a twist, where various special symbols can be collected through a speedboat and sometime also a wakeboarder. The game has a gigantic potential win of 25000X the bet which makes the spins extra thrilling, but the lower RTP of 94% is really something that we think they should increase. The theme is very entertaining, and the large number of thoughtful features make this gaming experience special and memorable.

Sumo Sumo is a slot where we get to meet these giant wrestlers, where through a fast-paced gaming adventure that involves Speedboats, among other things, you can scoop up wins of up to 25000X the bet.
