Flip a Coin
Flip a virtual coin for heads or tails, run quick series of 5, 10, or 100 flips, and track live heads/tails statistics and recent history.
Heads or tails
Use this coin flip tool when you need a quick two-way decision: heads or tails, first player, yes or no, left or right, or any other low-stakes choice.
- Click the coin, press Space when the page has focus, or use the Flip button.
- Run a quick series of 5, 10, or 100 flips.
- Track total flips, heads count, tails count, percentages, and recent results.
Series statistics
Each simulated flip is an independent Bernoulli trial with two outcomes. Short runs can look uneven, while longer runs usually move closer to the expected split without guaranteeing an exact 50/50 result.
X_n is the number of heads in n flips.
The history stores only the latest 30 flips in the current page session.
