BrainRush (spelled BrainRu$h) is a live-action game show on Cartoon Network, hosted by Lamorne Morris and, to a lesser extent, Sarah Karges.

Unwitting contestants are asked to answer trivia questions on roller coasters.

The show takes place at Knott's Berry Farm in Buena Park, California.

Street Wise: The host tells the player five letters of the alphabet during the ride.

Regurgitator: The player is read a short story (typically an article from USA Today) as the Silver Bullet moves up the lift hill.

Prior to the start of the final level, he/she is given the chance to eat a food item for a $100 bonus.

Afterwards, he/she is given the option of keeping all their winnings or risking half of it on one final question.

If the contestant gives the correct answer (the light turns green), he or she doubles his/her winnings and the coaster takes off immediately, however, if the answer is incorrect (light turns red), the contestant loses half of their total (the total is rounded down in the event of halving an odd amount).

The show premiered on June 20, 2009 as part of Cartoon Network's live-action programming block, CN Real.
