Jewel Miner

The directrion in which the jewels move when you click on them is apparently random, unlike every other game of this type where you have to either click and drag the jewel in the direction you want to move it, or click on the jewel, and then click a second time on tghe jewel you wish to swap it.

If you can get past the less-than-great controls and fairly limited size of the playing field, you should find this game quite enjoyable.
