Brain Train is an educational math game where players use math and dice to defeat or hold off an oncoming zombie horde. Player characters add special abilities and allow up to 4 players to join in a cooperative fight.
Each turn, players will roll 3 of their 4 six-sided dice. The fourth represents the player's life total. Using addition, subtraction, multiplication and division, the player will try to match target numbers on the zombie cards in order to stop or defeat the zombies. Players must use all 3 dice each turn. At the end of the turn, the remaining zombie cards move closer and new zombies join behind them. Players beware, if a zombie card moves close enough to attack you will lose one life point from your life die.
The game ends when the player has received 6 zombie bites or when the players have defeated the boss zombie.
