SudokuByte

SudokuByte is a calm place to play Sudoku, and to get better at it.

More than 10,000 rated puzzles, from gentle warm-ups to real brain-benders, with a teacher built in. When you get stuck, a hint shows you where to look first, then what to notice, then the move, one step at a time. You learn the technique instead of just filling in a number.

FREE, WITH NO ADS, EVER Every puzzle, every lesson and every hint is free. There are no ads, and there never will be.

LEARN THE LOGIC - 40 interactive lessons, from hidden singles to X-Wings, chains and unique rectangles, each taught on a real board you work through yourself. - Hints that teach: where to look, what to notice, then the move. - Plain-language explanations of every Sudoku term, right where you need them.

PLAY YOUR WAY - Classic: your own pace, with hints, pencil marks and automatic notes when you want them. - A daily puzzle, fresh every day. - Ranked: no hints, three slips, and a server that checks every move, so the leaderboards stay fair. - Honest difficulty: every puzzle is rated from 1 to 1000 by how many steps a person needs and how hard each one is. - Scores that reward accuracy and flow, and your stats by difficulty. - Share any puzzle or result with a friend.

THE AI TUTOR (OPTIONAL SUBSCRIPTION) Ask about any move on your board and get a patient, plain-language answer. The tutor explains why, never gives the answer away unless you ask, and checks what it says against the puzzle's solution. It is the one paid part of SudokuByte, because each answer has a real AI cost: a monthly subscription with a generous allowance that refills every month.

PLAY WITHOUT AN ACCOUNT You never need an account to play. Sign in with Apple, Google or email to sync across devices, play ranked, and use the tutor.
