Origami Speed Folding Race

Show every contestant the same origami model and its folding diagram before starting.

Give each contestant an identical sheet of square paper.

Start the timer and have contestants fold the model as quickly as they can from memory or the diagram.

A contestant who finishes raises their completed model for judging.

Judges check the folded model against the diagram for missed or sloppy folds.

The fastest contestant with an accurate, complete model wins; a flawed model is judged against the next-fastest correct one.
