Join Dave Lamb and Rattus Rattus as three more Horrible Historians travel down the time sewer to win year spheres. There are quirky quizzes, gory games and different eras, including the Rotten Romans.

And don't forget, you can play along too and collect year spheres of your own! Just download the Gory Games app from the CBBC website and join in the fun. If you're of a nervous disposition, a bit squeamish or easily shocked, then this show is not for you. Show less
