And a description:
BrainSurge is Nickelodeon's new kids game show where contestants will be put through four levels of games and puzzles that test their memory and comprehension skills. From puzzles that test their quick eye and reflexes to funny stories that test their ability to pay attention, as well as concentration games where making a perfect match can mean advancing to the next level.
Watching BrainSurge is like participating as the audience is able to play along with all of the puzzles and stories and matching games.
Winners from each round move on while those who don't qualify for the
next level go down the BRAIN DRAIN to get SLIMED.
