Sumoku is a captivating game of digital numbers where your objective is to create combinations totaling 10 by sliding them across the grid. You can move digits horizontally or vertically, effectively "flipping" them into the correct position. The digital nature of the numbers allows for interesting transformations, like turning a 2 into a 5 or a 6 into a 9. However, be cautious not to create non-numbers during this process. Special green and red digits add a strategic twist by offering powerful bonuses.

The game offers three engaging modes to play: Classic, Puzzle, and Endless. In Classic mode, you aim to eliminate a specific number of digits swiftly. Puzzle mode challenges you to clear prearranged number groups using the fewest moves possible. Endless mode lets you achieve the highest score before the grid fills up. Sumoku also features iCloud and Game Center support, including Leaderboards and Achievements, and offers two visually appealing themes: Light and Dark.
