(Android 4.0+, Universal) 7x7 is a puzzle game where you maneuver colored squares on a board, trying to put together four of the same color to make them disappear and get points. To clear the squares of the same color and get points, you can't just join them however you want. It only works if they form a straight line. You can't make squares or L-shapes; it has to be a vertical or horizontal line of squares of the same color.
