Crashbox is an educational children's television game show that airs on the HBO Family digital cable television channel in the United States. It aims to educate grade-school children in history, math, vocabulary, and other various subjects. The show takes place in the insides of a game computer where green game cartridges are created and loaded by rusty robots. Each half-hour episode consists of at least seven 2-to-5-minute educational games. Near the end, the robots will do "Crashbox Rewind" where they flash back through the show and remind you how smart you really are.
