Balltris is a game which will force you to challenge yourself and test your puzzle-solving skills.
    For those who love Tetris and have mastered it, here is a greater challenge. This game is in some ways similar to tetris and in other ways, just the opposite. You could choose the game option to position the balls at the bottom of the screen and score before they stack up to the top. Alternatively, there is a goal to stack up the balls to the top of the game board. This is not as easy as it sounds as you are challenged by the two-color balls. These tend to piece similar pieces together making it difficult to stack up. You will need to be fast and strategic in order to score higher and faster. The interface of the game is appealing and there are a wide-selection of options to tweak the game interface to your liking with different sound effects and graphics.
    You will find that your best opponent is yourself and you will be engrossed in doing better than yourself.
