About this game
Click a square, then a number. Every row, every column and every box must hold each number once.
A number that clashes turns red. Pencil writes small numbers to help you remember. Stuck? Hint shows the square to fill next, and why.
Easy is a 4 by 4, Normal a 6 by 6, Hard the full 9 by 9. A new grid every day, the same for everyone; then play practice grids as long as you like.
Keys: arrows to move, 1 to 9 to fill, Backspace to rub out, P for pencil, Z to undo.
