In Trial by Trolley, one player acts as the trolley operator and must decide where to send a murderous, out-of-control trolley. Every other player at the table plays cards and argues to convince the operator to spare their lives and condemn everyone on the other track to a gruesome death by trolley. In each round, one player serves as the conductor. This person will be the judge and select which track the trolley will kill. All other players will be evenly divided into teams, and each player has a role for the round. At the start, one player draws three angel tracks, chooses one to play at the table, and then randomly reveals a second angel track from the deck to be added to the chosen track. Another player draws three demon tracks and adds one to the opposing team's track in an attempt to sabotage it and spare their own tracks. Finally, players draw track modifiers that they can place on any track card on the table. They can play on their own tracks to influence the judge or on their opponents' tracks to further persuade the judge to kill their opponent's track. The judge will ponder this dilemma and ultimately decide to kill one track. The spared track is the winner of the round! The game continues for a number of rounds determined by the number of players at the table.
