Developed by the Swiss team Etter for the iPad and iPhone, Drei is a collaborative puzzle game where three players are tasked with working together to build a tower. A novel idea as far as video games are concerned, the team at Etter were not only interested in making a game or art (which Drei does well) but also a social experiment of sorts.
You know how to stack things on top of other things. We all do. You've been doing it since you could wrap your infant fingers around wooden blocks.
Drei is one of those quirky games that one will find hard to explain to friends, but it's a game that has a sense of charm which just can't be passed up on.
