A quick probability lesson
Over many flips, heads and tails each come up about half the time, but short streaks are completely normal. In 20 flips, a run of four or more of the same side happens more often than not. Use the results history to show students how random sequences really look.

Frequently asked questions
Is the online coin flip really 50/50?
Yes. Heads and Tails each have exactly a 1 in 2 chance. The result is picked with a cryptographically secure random number generator, so it is arguably fairer than a real coin, which can be slightly biased by how it is tossed.
How do I play best of three?
Spin three times and check the results history under the entries box. Whoever wins two of the three flips wins.
Does the previous flip affect the next one?
No. Each flip is independent. After five heads in a row, the next flip is still exactly 50/50.
