House of Conundrum transports visitors back in time, giving them the opportunity to alter pivotal moments in American history. Well, sort of. Instead of hopping into a time machine, visitors immerse themselves in historical escape-room scenarios, including Saving Lincoln and Rescuing the Revolution. During the first scenario, players must thwart John Wilkes Booth's assassination of the nation's 16th president; during the second scenario, they have to figure out if a particular revolutionary is a friend or someone determined to keep the British tradition of naming every dog Alastair alive in the Colonies.

Players have 60 minutes to uncover and solve all of the clues in the themed rooms. House of Conundrum also mystifies participants with the accursed Tomb of Doom and the nautical-themed 20,000 Leaks Under the Sea, which requires groups to MacGyver their way out of a sinking ship.
