Question 1

How many coins can I flip at once?

Accepted Answer

You can flip between 2 and 100 coins simultaneously. Each flip is independently random using the Web Crypto API.

Question 2

Why doesn't it always show exactly 50/50?

Accepted Answer

Each flip is independently random, so short runs will show variance. Over thousands of flips, the distribution converges to 50/50 — this is the Law of Large Numbers.

Question 3

What is this useful for?

Accepted Answer

Great for probability experiments, statistics homework, demonstrating the law of large numbers, and any scenario requiring multiple independent binary outcomes.

Question 4

Is each coin flip truly independent?

Accepted Answer

Yes. Each coin uses a separate random byte from crypto.getRandomValues, making every flip statistically independent of all others.
