Kyu Sudoku

A calm, paper-textured sudoku for iPhone. Solve the day's puzzle, climb a quiet ladder of rank, and keep your data to yourself. DAILY CHALLENGE One board a day, shared by every player and reset at midnight. Solve it against the clock, keep your streak alive, and see where you land on the public leaderboard, ranked by solve time. The top three wear a mark beside their name. There are no hints in the Daily Challenge, so the race stays fair for everyone. OR JUST PLAY Four difficulties from Easy to Expert, at your own pace. You can hide the clock if it makes you rush. Three mistakes ends a game, but you can take one second chance and the run still counts toward your best time, stats and badges. HINTS ON YOUR TERMS Every puzzle comes with two free hints, and you can turn that down to one or zero in Settings. Need more? Earn up to three bonus hints per puzzle with a short ad, or unlock them…
