About this tool
A coin flip is the simplest fair decision there is, and this tool brings it to your screen. Use a single toss to settle a choice, or flip hundreds at once to watch probability even out.
Every result is shown along with a running count of heads and tails. The outcome is drawn from your browser’s cryptographic random generator, so it’s genuinely unpredictable — no loaded coins here.
Frequently asked questions
Is the coin fair?
Yes. Each flip has an exactly even chance of heads or tails, drawn from the browser's cryptographic random generator.
Why flip thousands of coins?
It's a neat way to see probability in action — flip 1,000 coins and the split lands close to 50/50, illustrating the law of large numbers.
