About this calculator
A coin flip tool simulates tossing fair coins. Flip a single coin to settle a decision, or flip many at once to see the split of heads and tails — a quick demonstration of probability. A new flip happens whenever you change the number of coins.
Frequently asked questions
What are the odds of heads or tails?
A fair coin has a 50% chance of each on every flip, independent of previous flips. Over many flips the counts of heads and tails tend to even out, but any single flip is still an even bet.
Can I flip many coins at once?
Yes — set the number of coins and the tool flips them all together, showing the total heads and tails. Flipping hundreds at once shows how the ratio approaches 50:50 as the count grows.
