Your inputs and results never leave this device.
Flip a coin without searching your pockets. Heads and tails are equally likely, and each flip is independent. The running counter shows how the results are distributed over a session.
Use it for quick decisions, classroom probability experiments, or settling who goes first. The coin animation is decorative; the result itself comes from a secure random integer.

Frequently asked questions
Is a coin flip really 50/50?
A fair coin has a 50% chance of heads and a 50% chance of tails on every independent flip. The digital version uses an unbiased random choice, so previous flips do not affect the next one.
If I get five heads in a row, is tails more likely next?
No. Each flip is independent. Five heads in a row is uncommon but does not change the next probability; this is the gambler's fallacy.
Can I flip multiple coins?
The page is optimized for single flips with session counters. Use the random number generator with a 0–1 range for larger batches.
Is the flip recorded?
No. Counters exist only while the page is open and are not sent to a server.
