Klax

If you have a choice, and are looking for the best portable Klax (and in my opinion the best one out there), then get this version. It features countless hours of good and challenging enough for most - color matching, and great modes and unlockables to have fun with. Now Klax for me has been hard so far, but it makes me want to play it and get much better with it. I say that this version and the US Genesis versions are two of the best, and I wouldn't be so puzzled if you own and play both versions. Have a KLAXing good time.
