When discussing "Why study History?" with students, I often used to add a humorous anecdote by saying "How will win at Jeopardy (or insert other Game Show here) if you don't study History?" History accounts for a lot of Game Show quiz questions. Not that is is the only reason why we study History, but students enjoy feeling like they are on a game show.
In that spirit, check out the Ultimate History Quiz (from history.com).
Players can play single player, mutliplayer, or friend-to-friend competitions. Questions are from various history subjects.
