Classic tool
Coin Flip
Flip a coin online, run multiple tosses at once and track counts, percentages and longest streaks.
Use this coin flip tool when you need a quick heads-or-tails decision without a physical coin nearby. It works for one immediate toss or for a larger simulation, which makes it useful for tie-breakers, classroom activities, lightweight games and simple probability checks.
Instead of showing only the latest result, the tool also tracks how many heads and tails appeared, the percentage share of each side and the longest streak inside the current session. That gives you a better view of short-run randomness when you simulate several tosses in a row.
If you only need an instant answer, use the single-flip button. If you want to watch a bigger sample, enter the number of tosses and run the batch simulation in one click.
Use clear inputs to get a more useful result.
Why use an online coin flip
This page is useful for fast decisions, tie-breakers, games, classroom activities and simple probability experiments. Because the toss is instant, you can make a choice quickly or repeat the process many times without handling a physical coin.
What the summary tells you
The counts show how often each side appeared in the current session. The balance line shows the percentage split, while the longest-streak value helps you see how often the same result repeated without interruption.
Single toss vs batch mode
- Single toss: best for an immediate yes-or-no style decision.
- Batch mode: better for checking percentages and short streak behavior.
- Reset: clears the current session and recent history.
