Rules and Gameplay

Sumo Showdown, a captivating online slot machine by OneTouch, offers a unique gaming experience on a 4×4 grid with 10 paylines. Set against the vibrant backdrop of a sumo wrestling ring, players are treated to an atmospheric blend of Japanese music and cheers from an eager audience. Gameplay begins by selecting bet sizes ranging from $0.10 to $10, allowing for a maximum total bet of $1,000 spread over the paylines. The game’s intuitive design and straightforward mechanics make it accessible to both novices and seasoned slot enthusiasts, promising an engaging session filled with the spirit of sumo.

Bonus Features

Sumo Showdown shines with its innovative bonus features, designed to enhance the player’s experience and increase their chances of winning big. Key features include:

  • Wilds: The sumo referee symbol acts as the wild, substituting for all symbols except the sumo wrestlers, aiding in forming winning combinations.
  • Sumo Bout Respin Feature: Triggered when competitors appear on reels 1 and 4, initiating a respin that multiplies the total bet by 2. During the respin, up to 16 wild symbols can randomly appear, significantly boosting winning potential.

This combination of features ensures that each spin can lead to exciting outcomes, with the chance to cover the grid in wilds for even bigger wins.


The Sumo Showdown slot boasts a diverse range of symbols, each adding to the rich tapestry of the game’s theme. Symbols include:

  • High-Paying Symbols: The highest paying symbol is the sumo referee (wild), followed by the winner’s trophy, mountain landscape, Japanese lady, bamboo tree, and Japanese tea.
  • Low-Paying Symbols: Traditional card symbols from A to 9 represent the lower-paying icons, adding a classic slot feel to the game.
  • Non-Paying Symbols: Sumo wrestlers, which trigger the game’s respin feature rather than offering direct payouts.
