How it works +

Tosses are independent; heads and tails each have a theoretical probability of 50%. Share = outcome count ÷ total tosses. Global results aggregate all tosses.

Random source: Node.js on the server, crypto.randomInt(2). 0 means tails, 1 means heads. Each result is saved after generation.

Opening or reloading this page, or choosing “New session”, starts a new series. There is no time-based expiry. Earlier series remain in the global totals.
