Hivemind is a free online party game where players think alike. Each player gets spectrum cards (e.g., Hero vs Villain) with a hidden target. Everyone writes a clue describing its position. Then, one spectrum is shown with only the clue, and others guess where the target lies. The closer the guesses, the more points scored. The clue-giver also earns more when others guess well. The goal is to read each other’s minds and align thinking.
