Sumoku is a board game released in 2010 for 1–8 players, 15 minutes per game, and ages 9 and up. It was designed by Thierry Denoual and its main mechanics are Variable Player Powers, Cooperative Game, and Team-Based Game.
Sumoku is a crossword-style game with colored number tiles that can be played five different ways. In all Sumoku games, game play starts with the roll of a die to create a "key number" – either 3, 4 or 5. The digits in all groups of tiles placed in rows and columns must sum to a multiple of this key number. A tile is one of six colors, and a color cannot be repeated in a connected set of tiles. In the main game, players draw eight tiles to start the game. On a turn, a player adds a single row or column of tiles to the playing area to create valid plays – that is, the sum of the tiles played and all rows or columns added to during that turn sum to a multiple of the key number. The player scores the sum of the tiles played, and the sum of tiles in any row or column added to during that turn. If you finished a row or column of six tiles – that is, one with all six colors – you take another turn immediately before refilling your hand to eight tiles. The game ends when no one can play, and numbers in hand count against a player's score. High score wins. Other games include "Speed Sumoku" in which players each have ten tiles and try to create a crossword-style grid in which all sets of tiles sum to a multiple of the key number before anyone else. "Team Sumoku" plays similarly, but with each team creating one grid. "Spot Sumoku" has players trying to spot four tiles that sum to a multiple of the key number rolled from a public array of ten tiles. "Solo Sumoku" tasks a player with drawing 16 tiles and creating a legal grid from them, then drawing ten more tiles and adding them to the existing grid in a legal manner, then doing this with another ten tiles, and so on through all 96 tiles.
Sumoku supports 1–8 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Sumoku is 15 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Sumoku for ages 9 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Sumoku has a complexity rating of 1.4 out of 5 from BoardGameGeek players, which makes it a light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
