About the Coin Flip
A coin flip is one of the simplest fair random decisions we have — two outcomes, each with a 50% chance, and no memory of the last toss. This tool recreates that experience in the browser with a realistic 3D animation and truly random results powered by the same cryptographic primitive used for TLS and password managers. Everything runs locally: no network requests, no analytics on your result, no ads between you and the coin. Flip a single coin, batch up to 100 tosses for a probability demo, or leave it running to watch statistics converge toward 50/50.
Common use cases
- Settling a decision fairly between two options. - Choosing who goes first in a game or match. - Teaching probability, independent events, and streaks in class. - Running quick Monte Carlo demos with 50–100 flips. - Breaking ties in team meetings and pair-programming rotations.
Tips and tricks
- Press the space bar for the fastest possible flip loop. - Turn down the animation speed to 0.3× when demonstrating a single dramatic toss on screen. - Use a batch of 100 flips to show that short streaks are normal — a run of 5–7 heads in 100 flips is expected. - Copy the full history to paste into a stats worksheet or spreadsheet.
Limitations
- The animation is cosmetic; the outcome is decided the moment you click Flip. - History is stored only for the current tab and is cleared when you reset statistics or reload. - Native sharing is only available on browsers that support the Web Share API; on others, the share button copies the result to your clipboard.
Key features
A smooth CSS 3D flip with configurable speed makes every toss feel like a real coin spinning in the air.
Results use the browser's crypto.getRandomValues API, so heads and tails are truly 50/50 on every flip.
Toss a single coin for a quick decision, or generate a batch of up to 100 flips at once for probability demos.
Choose a generic coin, US quarter, euro, or British pound — each with its own colors, edge, and typography.
