About this game
Sudoku asks you to fill each row, column and three-by-three box with the digits 1 through 9 without repeats. The grey-boxed numbers are fixed clues; the remaining cells can be edited. A keyboard cursor marks your current cell, so no mouse is required.
Use the arrow keys or WASD to move, type 1–9 to enter a number and press 0 to erase your own entry. The game keeps a timer and a decreasing score, with separate controls for pausing, restarting and displaying help. Its native help explains the scoring and the built-in answer option.
This is Abhijeet Meshram’s 2005 freeware release for DOS. Press H at the title to read the instructions before selecting a difficulty. The original version 1.0 is preserved; the website’s Chinese explanation does not change the game’s English interface.
