Is the coin flip completely random?

Yes — we use the browser Math.random() function, which produces cryptographically strong randomness. Heads and tails are equally likely (50/50).

What is a coin flip used for?

A coin flip is great for making decisions (who goes first?), game rules, teaching probability, or simply for fun.

Can I flip multiple times?

Yes! The statistics show the heads/tails distribution and percentages across all flips. The history shows the last 20 flips.

Is the coin flip really random?

Yes. The tool uses the browser cryptographic random generator (Math.random), which gives an even 50/50 probability for heads and tails on every flip.

Coin Flip

Flip a virtual coin and get heads or tails. Animated coin toss with flip history and statistics.

↑ Flip coin

This coin flip settles heads-or-tails decisions instantly without a real coin. The animated flip returns a random result and keeps stats across your flips, so you can see how a longer run is distributed.

How the calculator works and what it’s for▾

How the randomness works

Each flip has an equal chance of heads or tails. The tool draws the outcome fairly, so any single flip is pure chance and does not depend on previous results.

Over many flips the share of heads and tails moves closer together, which is reflected in the stats it collects.

What a coin flip is good for

It is ideal for a fair choice between two options: who goes first, who buys the coffee, or which way to go. It is also a quick way to make a decision when you would rather not choose yourself.

The stats view is useful in teaching too, when illustrating probability and the law of large numbers.
