Trap Door Maze - Probability

My kids keep coming back to this maze, each time discovering how the trap doors teach probability in a fun, hands-on way.

The little trap door mechanism genuinely surprised me — you think you've got the odds figured out and then it drops your marble somewhere else entirely. We've been passing it around the dinner table all week arguing about which path is actually the smart bet.

My 8-year-old figured out the trap door mechanic in about ten minutes and now she's explaining probability to me at dinner. The little doors that flip and drop the marble keep her coming back way more than a plain worksheet ever did.
