Flip N times

About this tool

Flip a fair virtual coin in your browser using cryptographic randomness, with a running tally and a bulk-flip mode.

Is the flip fair?

Yes — each flip uses crypto.getRandomValues, giving an even 50/50 chance of heads or tails.

What does flip N times do?

It flips the coin the chosen number of times at once and reports how many landed heads versus tails.
