Baekdoku - Infinite Sudoku

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.
Every one of the 100 is free to play.

◆ Infinite Generator
Complete the 100 and the infinite practice opens.
Beginner to intermediate puzzles, generated endlessly in sets of 100.
One Premium purchase unlocks it and removes the ads at the same time.

◆ 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.

◆ Our Ad Policy, Stated Plainly
· Your first 3 puzzles have no ads at all.
· From the 4th puzzle on, one interstitial ad appears every 2 puzzles, with a minimum 90-second gap.
· There are no banner ads.
· A single Premium purchase removes ads completely.

[How It Works]
· Free to download — all 100 curated puzzles are free to play, with ads.
· Premium is a one-time purchase. It is not a subscription.
· Puzzles are bundled in the app, so you can solve offline (ads require a connection).
· Install and start playing right away — nothing to register.
