Gem Spinner is a genre masher, combining Bejeweled and Tetris.
The field is full of different "pieces" each containing several colored gems. You need to make 3 consecutive gems (horizontal or vertical only) of same color. The catch is, you can only move gems INSIDE the piece. You cannot shift a gem across two different pieces. If you remove gems, that square turns "dark" and gems are removed, and more gems drop from above to "fill" the pieces. If you don't see obvious possibilities, you can "rotate" pieces (double tap the piece) 180 degrees and see if that gives you more ideas. If you turn ALL squares of the piece dark, that piece is removed from the board. The idea is to remove as many pieces as possible before the time limit expire. You can actually MOVE the pieces around when you have removed a few pieces already and have some room to maneuver.
Too complicated? Yes. It's hard to keep track of all this stuff in your head. Not a bad idea, but a bit too complicated for action puzzler.
