Fair Random Selection & Client-Side Execution

Coin Flip uses the native Web Cryptography API (window.crypto.getRandomValues) to generate true unbiased entropy rather than predictable pseudo-random formulas. Each coin toss is predetermined with unbiased 50/50 hardware entropy before the smooth 3D animation settles on Heads or Tails. Your data and lists are processed entirely on your device and are never sent to external servers.

Frequently Asked Questions

Common questions about virtual coin tosses, fairness, and probability.

Is the Coin Flip tool free to use?
Yes. The Coin Flip tool is 100% free with unlimited single and multi-coin tosses and no ads blocking your decisions.
Is the online coin flip truly random?
Yes. Outcomes are generated using the browser’s native Web Cryptography API (window.crypto.getRandomValues), ensuring unbiased 50/50 hardware entropy before the visual coin animation runs.
Is Heads exactly 50% likely on every flip?
Yes. Every individual coin flip has exactly a 50% probability of landing on Heads and a 50% probability of landing on Tails, with zero bias.
Can I flip multiple coins at once?
Yes. You can toss between 1 and 10,000 coins in a single click to test probability, view exact counts and percentages, and inspect streak statistics.
Why isn’t a small sample of flips exactly 50/50?
Each flip is an independent trial. In small sample sizes (such as 10 flips), variance is expected (e.g. 6 Heads and 4 Tails). As the sample size increases toward thousands of flips, the distribution converges toward 50% pursuant to the Law of Large Numbers.
Are my coin flip results sent to a server?
No. All calculations run locally in your web browser. Session stats and recent history stay private on your device.
