How to use the Fair Online Coin Flip

A coin flip is the smallest possible randomizer: two named outcomes with an equal chance. Its value comes from a clear rule chosen before the result appears.

Assign the two outcomes

Say which action belongs to heads and which belongs to tails. Both must be acceptable before the flip.

Notice your reaction

The instant hope for one side can reveal a preference. You may use that signal before flipping, but do not rewrite the rule after losing.

Keep the stakes proportionate

Use a coin for a true tie or turn-taking rule. Unequal consequences need a comparison, a conversation or qualified advice.

Best used for

Two-option ties, choosing who starts and other reversible, low-stakes decisions.

Choose another method when

Health, money, safety, consent, legal rights or any outcome one person cannot freely accept.

Worked example: Deciding who starts

Two players agree that heads means Alex starts and tails means Sam starts. They set the rule before the flip and use the first result. The coin decides turn order; it does not decide whether either player can participate safely.
