• Illustration — A typical puzzle within the game. Toon-Doku follows the same principles as the logic-based puzzle Sudoku. In Toon-Doku, players have to fill a 9×9 grid with different symbols; however, no line or 3×3 subgrid can feature multiple of the same symbols. One of Toon-Doku main gameplay points is the player's ability to draw custom symbols for use within the games puzzles. The game also has several unlockable symbols, which can be obtained by completing certain puzzles. Toon-Doku features three main single-player modes: the instant mode, where players can play over 250 different sudoku puzzles, the stage mode, which features nine different levels, each with eleven puzzles, and the "Vs. CPU" mode, where the player competes against a CPU. Levels in the stage mode end with a boss fight, where an enemy can hide some of the boxes in the player's grid. Additionally, the game also features a multiplayer mode, where the player can hide some of the boxes in their enemies grids, similarly to the game's boss fights.

Toon-Doku was developed by the American video game development studio Dragon's Den Unlimited. The game was published by Majesco. The game was intended to be more suitable for younger players than traditional sudoku, which was attempted via the game primarily using symbols, instead of numbers. The game was first announced on January 24, 2007, by its publisher, Majesco, with a scheduled release of April later that same year. Toon-Doku released on April 10, 2007, in Europe, with a North American release following on April 16. The game released in Australia on October 12.
