Need to settle something fairly and nobody carries coins any more? Flip this virtual coin. It spins with an animation, lands on heads or tails with an honest fifty-fifty chance, and keeps score as you go: total flips, how many heads and tails, the percentage split, and the current streak. It is the quick, neutral referee for everything from kick-off choices to deciding who makes the tea.
The Session Statistics
Single flips settle single questions, but the statistics are where it gets interesting. Over many flips the percentages drift toward fifty-fifty — the law of large numbers in action — while the streak counter records runs of the same side. Watching a streak of seven heads appear, and knowing each flip was still fifty-fifty, is the most memorable probability lesson a coin can teach.
How to Flip
- Agree the call: which side wins the decision.
- Click the coin or the flip button.
- Watch it land and read the result.
- Flip again for best-of rounds, and check the session stats any time.
Everyday Decisions
Kick-offs and first turns in games. Choosing between two restaurants, two routes, two names. Teachers demonstrating probability with real tallies instead of textbook claims. Because the flip uses your browser's random generator and keeps no favourites, both sides can trust it more than the conveniently found coin in someone's pocket.
Frequently Asked Questions
Is the flip really fifty-fifty?
Yes. Each flip is an independent random choice with equal probability; past results do not influence the next one.
What does the streak mean?
It counts consecutive identical results — for example, four tails in a row. A long streak is unusual per run but expected eventually over many flips.
Do the statistics survive a refresh?
No. They belong to the current session and reset when the page reloads.
