Sudoku Solver
Solve any Sudoku by tapping numbers or pasting a grid, or generate new puzzles by difficulty with a reveal-able solution.
Blue = your entries, grey bold = puzzle clues, red = conflict. New puzzles are generated by filling a random valid board, then removing clues while a solver guarantees exactly one solution. Click a cell then a number (click again to clear).
