uNu Ecopak: Pack the Eco!

Imagine you're really important, so important that you need a bodyguard. But you're also tired all the time. Wouldn't it make sense to find a bodyguard who's also a great barista to help keep you awake? Well, that's pretty much what these uNu cases are for your phone. They protect and charge.

About uNu

When a player has only two battery cases left and is about to play one of them, he/she must say "uNu!" to warn other players. If the word is not said and another player points out the error before the next player takes their turn, the original player must draw two battery cases as a penalty.
