JawGrid is a very attractive PC-Clone of the adictive JawBreaker (c) Game from the Pocket PC. It might be explained as a mix between MahJong and Tetris. However I use balls or even ducks instead of bricks. The rules are rather simple but nevertheless the game play becomes very amazing as soon you start reaching for high scores. There are four different modes for playing (normal, shift, add mega row, add mega shift row)
