Planet Puzzle League review at Gamespot.

"Planet Puzzle League is the latest block to drop in an old series of simple puzzle games known as Puzzle League (or Panel de Pon). The idea in these games has always been to shift like-colored blocks into rows or columns of three, prompting them to politely vanish. It should sound familiar, and not just because the series has been around for 15 years. Everyone, at some point in their gaming career, has matched colored blocks and made them disappear. So what separates Planet Puzzle League's colorful cubes from the other blocks, jewels, and pills you've sorted in your life? Two things in particular: The DS stylus, which makes sorting blocks easier than ever before, and global Internet play, so you can challenge the square-pushers of the world. These two new features make Planet Puzzle League a nice place to revisit, though its staying power is questionable."
