Sumo Sumo Slot Review

The Sumo Sumo online slot is a game so good, they named it twice! Based on the hugely popular form of Japanese wrestling, this five-reel, five-row slot features stacked Sumos as multiplier wilds that fight for respins as they move across the screen. Sumos in speedboats feature in a fun bonus game.

The Streets of Tokyo 

There’s a nice cartoon style to the Sumo Sumo slot machine that brings a cheerful twist to the sport. You’ll see cube-shaped fruit symbols, plus two westers in red or blue loincloths on the reels, against a side-street backdrop. 

Japanese culture comes to desktop and some of the best mobile optimized online casinos via Swedish developer, ELK Studios. 

Choose Your Stakes

This is a medium volatility game with average returns of 94.0%. You can play the Sumo Sumo slot online for between 0.20 and 100.00 to win prizes from matched symbols across any of 259 ways. Here’s what each symbol pays as a multiple of the stake –

Stack Your Sumos

Sumo symbols can stack several high on the same reel. These heavyweight characters then become wild symbols with a multiplier equal to the number of wrestlers piled one on top of another. These multipliers combine if several sumos are in a win. 

The stacked wilds then walk one reel to the right as other symbols respin. If they reach the right-side reel, they then walk to the left and respins continue for as long as you get a win, or the wilds reach the left reel. Matched sumo wilds will merge for a bigger multiplier, while different types of sumo fight to combine their values. It’s a fun, if complex, feature. Fortunately, you can play Sumo Sumo for free on this page to see how it works in practice. Stacked wilds lock in place during a free spins bonus round.

We’re not sure why ELK Studios picked speedboats, but the Speedboat feature is a fantastic round, triggered by Hazard symbols. It’s a respins game, where you have three lives which reset if symbols land on the same row or reel as the moving boat money symbol. Special symbols, such as a wakeboarding, ramp-jumping, and swimming sumos add or multiply symbol values. The round continues until you run out of lives, or fill the grid.
