For the third and final season, Brainsurge became Family Brainsurge, as families competed on the show just like Double Dare & Nickelodeon GUTS did.

The game was played the same as before except that the number of kid contestants was reduced to five and that they are accompanied by a family member with two others sitting in the audience. Plus there are now names for each level. Level one is called Brain Tease, level two is called Brain Fart where during the question portion, if the family in control gets stumped they must then yell out "Brain Fart", allowing their relatives in the audience to help out, and level three, the bonus level is called Brain Trip.
