I have to agree that this is one of my favorite games and one that has held my interest for quite some time. While I enjoyed the original Bejeweled, this version has all the gameplay of the original but the addition of the puzzle and endless modes really make this an exceptional game. You can play for 5 or 10 minutes if that is all the time you have and still get a good challenge. The elimination of all the typical game detractors in the endless mode (you do not die, run out of time, or get stuck where you can't continue) make for a great gaming environment.
Skaven has done a great job on the music, it is not too repetitive, nor distracting during gameplay. In addition the game keeps score of all of your statistics, how many gems you have captured, how many chains you have made, and how many hours you have spent on the game. Overall, this game represents an excellent value because of the fun factor.
Give it a try and I think you will really enjoy it.
