About the game

In Gamma Extra, every game drops you into the heart of the casteller world, where precision, trust, and coordination are everything. Inspired by the Catalan tradition of building human towers, this cooperative experience challenges your team to do one thing: build a human tower in complete silence… and dismantle it safely without collapse. There are no turns and no pauses. Everything happens in real time, as if you were performing in front of a packed town square. Without speaking or giving instructions, each player must read the situation, anticipate others, and act in perfect sync. One mistake is all it takes for the entire structure to wobble. Gamma Extra transforms non-verbal communication into the core mechanic, pushing your team to operate as a single, coordinated unit under pressure. Every successful tower is a shared triumph; every fall, a chance to improve your connection. Can you build the tower… and dismantle it like true experts?
