Wojtek is enthused about this tetris style online puzzle “Colour Triplets” and quite rightly too! A pretty simple casual game yet nicely done. It uses OpenGL so make sure you have proper drivers installed. You can find more games on this site that run nicely on netbooks, but this one is, in my opinion, the best one. The site offers online rankings, but there is little competition (at least for now). Unfortunately you cannot check your high-score in game – it opens your default web browser and you have to register in the service in order to play, but registertion is free and quick & painless.
