About Sudoku
Built-in 9 by 9 puzzles
Each reset picks one puzzle from the local built-in puzzle list. Given cells are locked, and empty cells accept only digits from 1 to 9; clearing an input returns that cell to blank.
Exact answer check, not a full solver
The Check button compares the whole board with the stored solution for the current puzzle. It does not provide hints, difficulty selection, a Sudoku solver, or live row, column, and box validation while you type.
