🪙 Coin Flip
Heads or tails, settled in one tap. Every flip uses cryptographic randomness, so the odds are a perfect 50/50 — which is more than can be said for a real coin. The history strip below tracks your streaks.
Frequently asked questions
Is a virtual coin flip really 50/50?
This one is. Each flip comes from crypto.getRandomValues, your browser's cryptographically secure random source. Physical coins are actually the biased option — a Stanford study found real flips land on the starting side about 51% of the time.
I got five heads in a row — is it broken?
No, that's probability doing its thing. In 50 flips there's roughly a 96% chance of seeing a streak of five somewhere. Each flip is independent: after five heads, the next flip is still exactly 50/50.
Can I use this to settle a bet?
That's what it's for. Flip in front of everyone — the animation and history strip make the result transparent, and neither player can influence the outcome.
