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.

If you think of getting one, think no further and place an order now. This little device is even nicer in reality than it looks. It’s addictive and hackable. A really neat idea and product.

Definitely a collectors item.. Go out and order more and give it to your kids or anyone who wants to learn electronics and programming.

Great little game! The lights are super bright also. Will be great when music festivals return to play while in long boring lines.

A nice and interesting application for Arduino enthusiasts. Unfortunately, the instructions for installing additional programs are too complicated.
