Try sliding the shapes together to leave out any gaps and form complete lines, and aim for some big combos to really increase your score.
Shapes spawn after each swipe, shapes that are the same color stick together. There are 3 different power ups to help clear a lot of squares at once. The game ends once there is no room left on the board for the new shape. The game is fairly easy to pick up, so less reading and more swiping!
