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?

Questions and answers
Gamma Extra supports 2–6 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Gamma Extra is 15–30 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Gamma Extra for ages 8 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Gamma Extra has a complexity rating of 2.0 out of 5 from BoardGameGeek players, which makes it a medium-light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
