Play Big Sumo™ for Free

The reels of the Big Sumo™ online slot are set right outside a stylized sumo arena, with stone statues of sumo wrestlers on either side. You’ll see other cultural elements such as cherry blossoms, drums, and wooden shoes. Playtech designed the game to have an exaggerated character design and theatrical animations that give the slot a strong personality that keeps you engaged. The sound design reinforces this idea as the drums, chants, and impact sounds adapt to the features, thus creating a sense of anticipation.

The Big Sumo™ online slot operates on a five reel grid that has three rows and 25 fixed paylines. This increases to 50 fixed paylines during the Big Sumo Feature. All winning combinations start on the leftmost reel and go right. The slot’s RTP is 95.94%.

Sumo Wild Symbol

The SUMO symbol is the Big Sumo™ slot machine’s wild. It substitutes for all symbols other than the Rice and the Big Sumo to help create or improve winning paylines.

Big Sumo

The Big Sumo symbol is also a wild, and substitutes for all the Big Sumo™ slot’s symbols other than the Rice. This only appears on reel 3 during the base game.

Big Sumo Feature

You’ll trigger the Big Sumo™ slot machine’s Big Sumo feature when landing Rice symbols on reels 1 and 5 along with a Big Sumo symbol on reel 3. You’ll receive five free spins. Each Rice symbol that triggered the game fills 1 Rice position in the Rice Stack. At the end of each spin, the Big Sumo jumps to the Rice symbols and eats them up. Eaten Rice symbols are added to the Rice Stack counter. Once the Rice stack counter is full, the Big Sumo symbol increases in size to cover more positions, and the counter resets. You’ll get one additional spin each time the Big Sumo symbol grows.

You’ll receive spins on the Big Sumo™ slot’s Mega Reel if the Big Sumo symbol reaches the maximum size. This feature takes place on a 5x5 grid with 50 paylines and can award you with a prize of between 70x and 350x your bet.

Triple Way Jackpots

You’ll trigger the Big Sumo™ slot’s Triple Way Jackpots when landing three or more scattered Gold Triple Way or Silver Triple Way symbols on the screen. Each triggering symbol awards one spin on the 3x1 reel on that reel. If the spin results in three Triple Way symbols, a super reel will appear and you’ll win a jackpot prize.

Buy Feature

You can purchase the Big Sumo Feature for 55x your stake.
