About Bubu Sudoku
Bubu Sudoku is a clean, focused Sudoku app for daily play and steady practice. Play a fresh daily puzzle, choose a difficulty, or pick Mini for a quick 6x6 board with 2x3 boxes. Use notes, undo and redo freely, track progress, and improve your solving speed over time. An optional local daily reminder helps you keep your streak — no account or cloud sync required. Sudoku Pro is a one-time unlock for Master and Evil difficulty, Killer Sudoku, Sprint and Marathon modes, and six months of daily history. Game Center support lets players submit best times to leaderboards by mode and difficulty. Local play works without an account.
