Matrices Inverse Diagonal
In Spots you must form lines(vertical, horizontal, diagonal) with the spots on the board. Lines are formed by aligning spots of the same color. The minimum spots you must align to form a line depends on the configuration. You may move a spot from one place to another only if there is a path...
