How it works: three bombs, four modules to learn — wires, keypad, button and simon — drawn from a shared bomb dossier (serial, batteries, indicator) that the rules cross-reference. The Defuser touches the bomb and describes what they see; everyone else reads the manual and calls out instructions — out loud! Roles rotate every bomb, so everyone gets a turn diffusing. Wrong move = strike, three strikes = 💥. Defuse fast for the most points.
