Zuma is an addicting game, the kind that sucks you in and only lets you go when the hunger or sleepiness are strong enough. The name of the game is to eliminate a bunch of balls relentlessly spiraling towards a sinkhole. Matching two or more balls of the same color makes them go poof!

If you're looking for a great timewaster for your smartphone or PDA phone, check out Zuma Mobile. It's a bit harder to control the game with a directional pad rather than a mouse, but the experience is more or less the same as on a desktop. The great thing about glu games' product page is that you can try out a flash demo of the game itself. So at least you can see if shelling out money for the download is worth it.

Just don't play this game while walking. It's so addicting that surely keep your eyes on your smartphone or PDA' screen, and you'll end up bumping a post or run into a speeding car!
