REQUIRES BASE GAME
The Robo Rally: Master Builder expansion features unique 6x6 game boards compatible with all previous Robo Rally releases.
Players can also customize existing boards with tokens, adding conveyor belts, gears, pits, and lasers to any board. Two of the 6x6 boards are a blank canvas, allowing total control of every obstacle. Become a master builder, and create the wackiest racecourses your engineering mind can dream up!
