Play Sudoku in easy, medium or hard with notes, hints and a timer, print PDF puzzle sheets with answer keys, or type in any puzzle to solve and check it.
Use the guide alongside the working tool.
Open Sudoku Generator & Solver →Pick the exam and document
Play: pick Easy, Medium or Hard and tap a cell, then a number (or type it). Switch on Notes to pencil in candidates; Hint, Check and Restart are always there.
Frame and clean up
Print: choose the difficulty, how many puzzles and how many per page, and download an A4 PDF with an answer key at the end.
Create and check
Solve: type in a puzzle from a newspaper or book (or paste 81 digits), press Solve, and see the answer, whether it has exactly one solution, or play it here.
Privacy and limits
Every generated puzzle has exactly one solution. Difficulty is set by the number of clues (and easy puzzles need only simple steps), so a few medium or hard puzzles may feel easier or harder than expected. Your game is saved in this browser only.
