Decision Spinner
Flip a coin or add custom options and let the spinner decide. Useful for settling debates, breaking deadlocks, and outsourcing the blame for lunch choices.

If you are using a random decision tool, you probably already have a preference. The value is in confirming it.
There is a well-known trick: flip a coin and pay attention to your reaction when it lands. If you feel relieved, that was probably the right call. If you feel disappointed, it was not. The spinner works the same way. Randomness is useful not because it makes the right choice, but because it surfaces how you feel about the options.
How we work it out
Coin flip picks heads or tails at random. Custom options picks one of your options at random, up to ten, and each one has the same chance. The spinning is for show. The result comes from your browser's random number generator, and every flip is independent, so the same answer can come up twice in a row.
Common mistakes
- Adding options you would not accept. Only put in choices you'd be happy with, or you'll spin until you get the one you wanted.
- Spinning again until you like the result. Agree before you spin that the first result stands.
- Using it for decisions that need thought, like money or health. It is best for tie-breaks and small choices.
- Leaving duplicates in the list, which makes that option more likely.
Questions
Is the result truly random?
Yes. The result is selected using JavaScript's Math.random(), which is a pseudorandom number generator. It is random enough for any everyday decision. It is not suitable for cryptography or high-stakes lottery applications, but it will fairly decide whose turn it is to make tea.
How many custom options can I add?
Up to 10. Each option is equally weighted, so the spinner gives each one the same probability of being selected.
When is a spinner a good way to decide?
It works well for tie-breaks and small choices, like where to eat, who goes first or which of two equal ideas to try. It is not for big decisions that need real thought.
What should I do if I do not like the result?
That is useful to know. If you wanted a different answer, it probably tells you what you really prefer. Agree before you spin whether the first result stands.
Decision made. Now something with actual stakes.
