## Description

Sudoku Solver is an online application for entering, generating, and solving Sudoku puzzles. Designed for players who want help with a challenging grid or wish to improve their solving skills, it works through puzzles step by step and explains the logic behind each move. Users can enter a puzzle manually, import it as a string of 81 digits, or generate a new puzzle at a selected difficulty, from very easy to fiendish. The solver offers hints, puzzle analysis, candidate highlighting, and a solution check that indicates whether an entered digit leaves the puzzle solvable. Players can also work through a puzzle independently, undo moves, replay a solution, and save or load puzzles. Completed or newly generated puzzles can be printed, with the option to include candidates. Sudoku Solver supports a range of solving techniques, including singles, locked candidates, subsets, fish patterns, coloring, wings, chains, and unique rectangles. The site also provides instructions for entering puzzles and navigating the grid, making its tools accessible to both casual solvers and experienced Sudoku enthusiasts.
