Coin Flip
Coin Flip
Tap the coin for heads or tails. Fair, instant, and no coin required.
How the coin flip works
Press Flip or tap the coin. The result is chosen by your browser's cryptographic random number generator, the same source used for security features, and then the coin animation plays. Heads and tails each have exactly a one in two chance, and one flip has no effect on the next.
Choose more than one coin to flip several at once. The result shows how many heads and tails came up, and the running totals below the coin keep count until you reset them.
When to flip a coin
- Settling a tie: who goes first, who picks the movie, who pays for coffee.
- Making small decisions: when two options are equally fine, a flip saves time.
- Finding out what you want: assign each option to a side, flip, and notice whether you feel relief or disappointment. That reaction is useful information.
- Games and classrooms: probability lessons and games that need a fair random bit.
For anything with more than two options, use the spin the wheel tool. To roll dice instead, try the dice roller.
Frequently asked questions
Is the online coin flip really 50/50?
Yes. Each flip is an independent draw where heads and tails are equally likely. A real coin can be very slightly uneven, depending on how it is flipped, but this one is not.
Can I predict the next flip?
No. Past results, including a streak of five heads in a row, do not change the odds of the next flip.
Are my flips saved anywhere?
No. The running totals only live on this page and disappear when you close or reload it.
Does it work on a phone?
Yes. It works in current versions of Chrome, Safari, Firefox and Edge on phones, tablets and computers.
