We focused on the joy of discovering the flow of the solution rather than the moment of correctly guessing the numbers.

Ketsu · SUDOKU offers three grid sizes—4×4, 6×6, and 9×9—and difficulty levels: Breezy, Focus, and Abyss. Choose a puzzle that fits your current rhythm, from a short break to deep immersion.

Key Features
• A stable generation system that verifies the unique solution for every puzzle
• Three sensory themes: Paper, Waves, and Night
• Candidate number memos and automatic memo organization
• Guides you to visible rule conflicts without predetermining the answer
• Insight hints explaining candidates and the reasoning behind the solution
• Smooth cell waves, FLOW combos, and completion animations
• UI sound effects that react to taps, inputs, collisions, hints, and completion
• Auto-save, continue, and playback history

Instead of rushing to fill in the correct answer, try connecting the texture of the numbers one square at a time.
