Wisdom Stone Sudoku

Wisdom Stone Sudoku is built for quick, focused logic practice. Open a level, study the grid, and solve one step at a time. Classic Mode gives you a calm 9x9 Sudoku experience. Brain Challenge adds a timer. Hell Mode raises the pressure. Training Mode lets you practice smaller board sizes before returning to full 9x9 puzzles. Helpful tools are included when you need them: notes, undo, erase, pause, hints, row and column highlighting, and local progress saving. Wisdom Stones can be used for hints, revives, and extra time. No account is required. Your progress is saved locally on your device.
