The game tests players’ skills of observation, reaction, memory, and coordination. Each game is made up of eight fast-paced challenges that force players to refocus their minds quickly as they race to solve each puzzle before their opponents. Players earn cards for being the first to accurately obtain the answer to the puzzles. Correctly identified tactile cards are worth twice as much as other challenges. Players can exchange a tactile card or two other challenge cards for a piece of the brain. The first player to accumulate four brain pieces wins.
