Brain Train is an educational board game created by Dave Waldrop that aims to improve critical thinking skills through the use of music. It is currently in the development phase and not yet patented or trademarked. The game is designed to be played with 5 players who take turns asking each other questions based on the lyrics of a song. Correct answers result in receiving a game chip, while incorrect answers require giving a chip to the other player. The goal is for players to observe improvements in areas like abstract reasoning, verbal skills, critical thinking, and conflict resolution. Currently located in North Carolina, Brain Train hopes to sell the idea to enhance learning for people of all ages.
