Click the board to randomize the setup.
Click one of the square tiles. The square and some other squares will change, each from red to blue to transparent.
 
Now we list which positions will be changed with each mouse click. We write 'ortho 3' short for 'position at a distance orthogonally of up to 3 steps', and 'diag 2' short for 'position at a distance diagonally of up to 2 steps'.
Variant 1: ortho 1
Variant 2: diag 1
Variant 3: ortho 2
Variant 4: diag 2
Variant 5: ortho 1 diag 1
Variant 6: ortho 2 diag 1
Variant 7: ortho 1 diag 2
Variant 8: ortho 2 diag 2
Variant 9: ortho 8
Variant 10: diag 8
Variant 11: ortho 8 diag 1
Variant 12: ortho 1 diag 8
Variant 13: ortho 8 diag 8
