Sudoku that respects your time, your eyes, and your data. Kilenc never makes a network request; saved games live in a JSON file on the device and nothing else.
- Three ways to play — a gentle Beginner ramp with helpers on, Standard across Easy through Expert, and Custom where you dial in clues, max technique tier, and intensity yourself. Every puzzle is guaranteed to have exactly one solution.
- Per-tile scoring with medals — faster placements score more, a finisher bonus rewards the last minute, and a stats sheet tracks best score, streaks, and time invested.
- Hints that teach, not spoil — tap Hint and Kilenc names the technique to apply (“Naked Single”, “XYZ-Wing”) instead of just filling the cell. 11 human-style solving techniques across four tiers, with an interactive How to Play tab.
- Built natively per platform — SwiftUI on iOS, Jetpack Compose on Android, laid out for tablets so the board breathes instead of stretching. Light, Dark, or follow the system.
No ads, no accounts, no tracking, no analytics — just the puzzle.
