About
A hundred meditations, and then infinity.
Baekdoku begins with one hundred carefully chosen sudoku puzzles and continues without end.
◆ 100 Curated Puzzles — Free
One hundred beginner-to-intermediate 9x9 puzzles, selected with care. Difficulty rises naturally.
Play every one of them free, with ads.
◆ Infinite Generator
Complete the 100 and the infinite practice opens.
Beginner to intermediate puzzles, generated endlessly in sets of 100.
One in-app purchase removes the ads at the same time.
◆ Samurai Sudoku (Premium)
100 Samurai puzzles: five 9×9 grids overlapping on one 21×21 board.
Shared cells must satisfy both grids. Pick a grid from the overview and solve it up close.
◆ Progress and Rhythm
Completion rate, average time, streak count. Watch your practice accumulate.
◆ A Meditative Experience
Brown and gold, a quiet interface. Time for your thoughts to clear.
