    Amazing little portable game board. I also have the first version and I have to say that the new bigger matrix looks very neat. It comes preprogrammed but the instructions found on this page make programing it with new games and scrolling messages very easy and fun! I totally recommend it and it also doubles as an incredibly cool keychain.
