Is the coin flip truly random?

Yes. Results are generated with window.crypto.getRandomValues(), which produces cryptographically secure random bytes, making each flip completely unbiased.

How many flips can I do at once?

You can flip between 1 and 1000 times in a single click. Entering 1 activates the animated single-flip view; entering 2 or more activates the aggregate stats view.

What does "longest streak" mean?

The longest streak is the maximum number of consecutive identical outcomes (all heads or all tails) in your flip sequence.

Does this work offline?

Yes. The tool is 100% client-side JavaScript with no external requests, so it works in any modern browser including offline.
