Temple of Cthulhu is a hidden-role social deduction card game for 3–12 players. Each player gets a secret role and five cards. Over four rounds, players place cards face down and make claims about what they’ve played — which might be true or false. The challenge is figuring out who to trust and who’s secretly working against the group. Investigators aim to uncover Elder Signs, while Cultists try to stop them and instead reveal Cthulhu Idols. The game blends bluffing, memory (to track past claims), and timing to play item cards that disrupt others’ plans. Junk cards add uncertainty, and winning hinges on convincing others you’re innocent — while pointing fingers at the right suspects. Ideal for party gamers who love betrayal with a dash of cosmic horror!
