Match three colors across or down to clear space on the board and keep racking up points. It's deceptively simple - or is it? There are fresh challenges as well as bonus options built into this puzzle game. StackThree works in several directions, and as long as you have a sharp eye and quick hand, you'll keep the board clear enough to accommodate what's incoming. If you haven't placed the pieces before they reach the right side of the screen, they'll start filling the board randomly. A bright and happy sound track keeps you focused.
