Command / sudokuClassics
Sudoku
The empty cell is only free until its row, column, and box speak
Place a digit, check the grid, and let the constraints do the arguing.
Enter a value with row-and-column notation such as `1a=5`, use notes to hold candidates, and ask for a check when you want the board to highlight mistakes. Every row, column, and 3x3 box must contain 1 through 9.
The terminal gives you a clean puzzle state and the same logical work as a paper grid, with hints available when you choose to spend the points.
