Joe C. Fitzgerald's

Conveyor

Made by Γ with the help of Claude

Meet the machine

Numbered boxes ride a conveyor belt — past a sensor, and over a trapdoor.

The faulty sensor

The faulty sensor is stuck in a rhythm: a box that trips it passes safely, and the trapdoor springs open under the very next box. Press Step to move the belt.

Around to the back

A box that is safe while exiting a loop is not finished — it rides off the end of the belt and rejoins the line at the back. Watch box 1 come around again.

Last box standing

The goal of the game: guess which box will be the last box standing.

The teacher bets blind

Joe C. Fitzgerald — without seeing which boxes you picked — decides their bet, in front of everyone.

Run the belt

Then you all watch as the belt discards boxes to the rhythm of its faulty sensor — until one box remains.
