If you have owned a PalmOS device in the past, sure you know this old blocks game that has roots in Puzznic. Ilker Aksen (developer of this game) is a big fun of Vexed since the 1st PalmOS version. Missing this game since he first bought a pocket pc made him create his own and now with all love over the xda-dev community, he has released it for free and it works awesome. You can download it for free and if you'd like to hit him up with something, head over here.
