I love Bejeweled and Jewel Quest. Puzzle games are a great relaxation tool. I know of a few other puzzle games, but I have not played them yet. I always seem to get sidetracked, and forget to check them out. Here is the description, for a puzzle game that I really want to play.
The UnderGarden- In The Undergarden, you play the role of a creature who has to pollinate all the plants you can find. The plants you have to tend all live in a vast and intricate sea-cave filled with strange life forms, dead ends, and… musicians. In order to fertilize the flora, you’ll have to use your brain and your environment to solve puzzles and find hidden treasures.
