Five heads in a row

The server generates independent fair tosses. Tails resets the streak. Five consecutive heads completes a round. Reload or choose “New round” to start over.

All tosses are saved. Mean waiting time includes only completed rounds, excluding unfinished attempts. The theoretical mean is 62 tosses. Early abandonment may bias the sample of completed rounds.

No registration. Everyone appears as “Anonymous”. Results update after successful submissions. Reloading does not erase shared history. The server stores participation records; the page shows recent entries.
