Design a Watertight Tiebreaker Round

Two teams finish dead level, the room's watching, and 'closest guess wins' feels like a cop-out. This designs a tiebreaker that picks a clear winner without pure luck, runs in under five minutes, needs nothing but pen and paper, and feels dramatic and fair. Three options from simple to elaborate, with the questions ready to go.

Design a tiebreaker system for a pub quiz where {NUM_TIED_TEAMS} teams are level on points after the final round.

Provide three tiebreaker options ranging from simplest to most elaborate, with full question content for each option. For each option explain the procedure, how to adjudicate edge cases, and any risks to watch out for during a live event.
