How to play 3Sudoku
You can work the whole thing out by playing it. Keep a hand on the arrow keys / WASD; everything else is listed in the controls table. The game is wide rather than tall — fullscreen is worth it on a monitor, and on a phone the picture is much better sideways. Most players get the hang of it inside two or three attempts.
