SudokuStreak

A new Sudoku puzzle every day, and everyone in the world gets the same one.

SudokuStreak is built for people who want to get genuinely good, rather than people who want something to tap at. There is no clutter, no advertising and no nonsense. One puzzle a day, a streak worth protecting, and a calendar that shows the shape of your habit.

The hint engine is the part that matters. Rather than filling in the square for you, it names the technique behind the next move, from naked singles through to pointing pairs, so the help you take is help you keep.

Beyond the daily there are four ways to play. Zen is untimed with mistakes uncounted. Speed Run puts you against the genuine fastest times. Killer adds cage sums and removes the givens. Practice is short drills that train one technique at a time.

Sign in and you get the daily leaderboard, friends, and a streak that follows you between devices. Skip the sign-in and the whole game still works offline with no account at all.

Pro is a single purchase rather than a subscription. It adds Expert difficulty, Killer and future variants, Speed Run, the practice drills, and the full accent colour palette.
