Background

Coin tossing is a form of sortition with two possible outcomes; used this way the coin serves as a binary lot. Many divination systems, from moon blocks to cowries, are built on binary lots.

How it works

You hold a yes/no question, flip, and read heads as yes and tails as no. Some people use the moment of flipping simply to notice which answer they were hoping for.

Notes and limits

Safety: A coin is pure chance. Do not let it decide anything serious.
