In The Big Bang Theory: The Party Game – originally announced as Bazinga!, after the "gotcha" catchphrase of the TV show's signature character Sheldon – players compete to pair category cards with insider phrases and references from the show. Players earn points based on how their card combinations are judged and ranked, and the player with the most points wins. Special "Bazinga!" cards add chaos and surprise to the game play. Every card includes a photograph from the show to highlight elements from the show.
