The numbers are placed on the wheel. It spins, slows down and stops on one of them: that number wins the prize. Beyond 50 numbers, a pre-draw of 50 finalists comes before each draw.
Overview
The winning number is revealed on a picker wheel: the wheel shows only 50 numbers, so it pre-draws those 50 before it starts to spin, which may need explaining to your audience.
When to use it
To give out a series of prizes while drawing out a long suspense: the number is revealed slowly.
The order in which prizes are given out
Prizes are given out in the order of your choice, each one as many times as it has copies.
How chance is handled
The result is drawn before any animation, and the animation is built from it. What appears on screen brings only spectacle and suspense; it does not choose the result.
