Crashbox is a Canadian- American 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 (which are sculpted out of clay) 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 review most of the games to the viewers.
Crashbox was one of the cornerstone programs for the relaunch of the HBO Family channel in February 1999. The series has never been released on DVD or VHS, but remains on HBO Family to this day.
