About CoinToss
cointoss.uk is a browser-based coin toss tool for heads or tails, custom choices, and sports toss scenarios. It does not require an account or download.
Our mission
The site offers a quick alternative when a physical coin is not available. Its result is generated in the browser, but the tool should not be treated as an official process for a regulated competition or high-stakes decision.
The site is designed to feel like a real coin toss: you see the coin, you trigger the flip, and you watch the animation land on heads or tails. The experience is immediate, visual, and satisfying — just like tossing a physical coin, but without the fumbling.
How the tool works
The coin tool uses the browser's crypto.getRandomValues() API and maps the returned value to one of two outcomes. The animation is visual; the result is selected before it plays. This describes the implementation, not an independent security guarantee. See how the toss is generated.
Multiple modes for different needs
The site offers five distinct modes, each tailored to a specific use case:
- Classic heads or tails — the standard fifty-fifty flip for everyday decisions.
- Best of three — a first-to-two series that ends after two or three flips.
- Custom choices — replace heads and tails with any two options: tea or coffee, pub or home, A or B.
- Football toss — decide kick-off or ends before a match, training session, or five-a-side game.
- Cricket toss — determine who bats or bowls first with a quick, fair decision.
Each mode has a standalone page for direct access.
Privacy and data
cointoss.uk does not require an account. On the main tool, flip history, statistics, coin preferences, and sound settings are stored locally in your browser using localStorage. Each single flip or completed best-of-three series also sends its outcome side, mode, and coin preset to the site's statistics endpoint; this request is separate from the browser-generated result. “Reset stats” clears local flip statistics and recent history, not the site's overall counters or saved preferences. See the privacy page for more details.

Why coin tossing matters
A coin toss can help choose between two options when either outcome is acceptable. For important decisions, consider the consequences rather than leaving the choice entirely to chance.
