Gamma Extra

Players cooperate in real time to assemble and then dismantle a human tower inspired by Catalan castellers. The game forbids verbal communication, so teammates must read body language, anticipate actions, and coordinate silently as the structure grows. There are no turns; all actions occur simultaneously and under time pressure. One misstep can destabilize the tower, so balance, timing, and mutual trust determine success or collapse.
