"The 1st time we went through the game they were mesmerized. The 2nd time they were laughing at themselves & each other...The 3rd time, they paused for a moment to invent their own rules & cards & we filled 2 hours with Robot Turtles. They want another board so they can build huge mazes & play with more people at one time. Did I mention that these are all middle-schoolers & not your intended audience? Thanks for such a valuable creation..."
