Blind Line is a lively, non-verbal team challenge where participants must arrange themselves in a specific order—such as height, birthdays, or years of experience—without speaking and often with their eyes shut or blindfolded. As the timer starts, the group experiments with touch-based cues, taps, and improvised systems to communicate. The energy is playful and chaotic at first, but teamwork, adaptive thinking, and trust quickly emerge as participants work together to form the correct sequence.
