As the original match-3 puzzle game, Bejeweled has spawned a legion of imitators over the years. We can attest to the fact that it is very simple to play yet addicting. Once you start it's hard to stop.

You begin with an 8 x 8 board filled with various jewels. You have to swap any two adjacent gems to create rows of 3 or more of the same type. When a line is cleared from the board new gems replace it.

As with all other applications released for the iPhone so far, Bejewled runs through the iPhone's Safari Web browser, and not directly on the device itself. According to PopCap, this customized version of Bejeweled has been optimized to take advantage of the iPhone’s unique display and touch controls.

Bejewled for the iPhone is free—simply log on to www.popcap.com via the iPhone’s Web browser to play. We tried this. When you go to that Web address you're automatically redirected to the game at http://static.popcap.com/iphone/.

We found gameplay to be a little slow with the iPhone. PopCap obviously couldn't completely overcome developing for a Web browser rather than an OS.

Keep in mind; because it is formatted for the iPhone, it may not look right in these other contexts.
