Sumo Sumo

Sumo Sumo is a five-reel, five-row slot from ELK Studios with stacked symbols, walking wild multipliers and respins. The game is built around a medium-high volatility model, with a stated RTP of 94% and 259 paylines. Players can use the demo version to play for free and practice before playing for real money.

The main features include Wild Sumo Stacks, formed when adjacent or winning sumos create a moving multiplier wild that can trigger respins. Two Free Spins symbols activate the free spins round, where Wild Sumo Stacks do not spin out, while the X-iter feature offers different entry modes into bonus play, including a higher-chance option and a free-spins variant.

A second bonus, the Speedboat Bonus, is triggered by collecting three bonus symbols and works as a hold-and-spin round with coins and extra feature symbols. According to the game data, the maximum win reaches 25,000x the bet, with wagers ranging from 0.20 to 100.
