Planet Puzzle League review at IGN.

"Planet Puzzle League is a fantastic example of Nintendo's recent evolution to approach gaming in a way that appeals not just to the hardcore gamer, but also to its newest pride and joy: the casual gamer. The title is simple a republishing of the company's addictive Panel de Pon design. Nintendo's finally settled on the branding Puzzle League in the US, and now it's about advancing and evolving the design to follow the advancements of the company's systems. Planet Puzzle League's core puzzle element is just as fun and addictive as it has been since its original NES/Super NES/Game Boy iteration, but the addition of major elements like touch-screen control and online multiplayer -- and even minor inclusions like a "Daily Play" option -- brings a ton more depth. And its classy, subdued presentation makes it even more approachable to the non-gaming crowd."
