Question 1

How does the decision wheel work?

Accepted Answer

Each entry is mapped to a slice of the wheel proportional to its weight. When you click Spin, the wheel is rotated with a randomized final angle and the slice that stops under the pointer is selected as the winner.

Question 2

Can I make some entries more likely to win?

Accepted Answer

Yes. Use the syntax 'name:weight' (for example 'Pizza:3') to give that entry three times the chance of being picked compared to a default weight of one.

Question 3

Is the result truly random?

Accepted Answer

Yes. The spin angle uses the browser's cryptographically-suitable random function, and the wheel is given several full rotations plus a random offset so each spin is unpredictable.

Question 4

What are common uses for a decision wheel?

Accepted Answer

The wheel is great for giveaways, classroom random picks, deciding where to eat, board game turn order, party games, and breaking ties between two equal options.
