If you like to shoot at things, break glass and solve puzzles all at the same time, then this is the game for you. Pull back on the ball, aim at a pane of glass, let go to shoot and break the glass. Use the direction arrows to control the direction the remaining panes move. Try to get each row or each column to be all one color. When you get every row or every column to be all one color you win. Try to win in as few shots as possible. There are three different grid sizes. (4x4, 6x6 and 12x12) But there are six levels of difficulty. Each grid size has two levels of difficulty. The easier level maintains a row or column as is once you achieve all the same color in that row or column. The harder level does not maintain rows or columns that are already all one color. You can take a break anytime, just close the app, it will remember your game and let you reload it when you start the app next time. If you would like to listen to music from your music library while playing, just turn the sound off, close the app, start your favorite music, reopen the app and play. The game stores the best score for each level, so play it over and over to try and beat your best score on each level. Good luck and have fun.
