Features
A physics-style 3D flip animation with randomized spin, exact 50/50 odds per toss, persistent heads/tails counters, streak detection, and a result announcement. Tosses are limited to one at a time so animations never overlap.
Benefits & Use Cases
Instant, indisputable decisions without hunting for a coin — useful for remote teams choosing who goes first or friends settling debates. The streak tracker adds fun to party games, and teachers can use long flip sequences to demonstrate the law of large numbers.
Tips
Streaks of 5 or more in a row are normal in random sequences — that is the gambler’s fallacy trap, not a rigged coin. For best-of series, agree on the number of flips before starting. Reset the tally between games.
Frequently Asked Questions
Is the coin flip truly 50/50?
Yes. Each flip uses your browser’s random source with exactly equal probability for heads and tails.
What does the streak counter show?
It shows how many times the current side has landed in a row, for example 3x Heads after three consecutive heads.
Can I flip best-of-five series?
Yes. Keep flipping and watch the tally; the side that reaches three first wins. Reset between series.
Why do I get long streaks?
Randomness naturally produces streaks. In 100 flips you should expect several runs of 5 or more — this is normal, not bias.
