Lady Santa's Signs & Colors is a 3 in a row matching game: by swapping cubes, you have to put selected cube near other cube matching by sign (and color).
When you have put 3 of them in row (horizontally only) they are removed from board.
If you cannot find more cubes, you can change sign (and color) using "change boxes".
When you have removed all cubes, you win a "perfect" round.
