Overview

Brain Chain is a trivia board game for 2 to 4 players (or teams) where the objective is to connect an unbroken row of “links” on a 10x10 category grid. Players move a shared yellow marker around the board’s exterior track using movement cards and “brain pills” (bonus cards earned by answering correctly). The game combines trivia knowledge with spatial strategy, as players must position their links to form a connected chain while blocking opponents.

Components

Setup

  1. Place the game board in the center of the table.
  2. Each player or team chooses a color and takes the corresponding link pieces.
  3. Shuffle the movement cards and place them in a draw pile.
  4. Place the yellow pawn on the starting space of the exterior track.
  5. Agree on the winning chain length: 4 links (quick ~30 min), 5 links (~60 min), or 6 links (~90 min).

Turn Structure

On each turn, a player:

  1. Plays a movement card (and optionally brain pills) to move the yellow pawn along the exterior track.
  2. Chooses a square on the 10x10 grid that is in the same row or column as the yellow pawn’s current position.
  3. Attempts to answer a trivia question from the category shown on that grid square.
  4. If correct, places a link on that square and earns a brain pill bonus card.
  5. If incorrect, no link is placed and play passes to the next player.
