This is the popular and classic gem swap type game. Connect three or more jewels in a row to earn more points. This app is basically the similar game as jewel match 3 games. If you enjoy jewel matching games, this is a great example of one on Android.
Jewels world I have 2 tablets, and on both, I can only get 3 gold stars to level 113. As soon as I hit another level, they all stay black. This really bothers me. I try hard to achieve 3 gold stars and it doesnt register that I passed that level. I really enjoy this game, but am considering uninstalling it. If it gets fixed, it would probobly be one of my favs and get 5 stars.
