Heads or tails, or yes or no
Choose Heads / Tails for a classic coin toss, or Yes / No to answer a question directly. Each flip uses your browser's cryptographically secure random number generator, so both sides have exactly a 50% chance.
What happens when you flip a coin 100 times?
You'll rarely get exactly 50 heads. In 100 flips, getting between 40 and 60 heads happens about 96% of the time, and exactly 50 only about 8% of the time. Streaks are longer than most people expect: the longest run of the same side in 100 flips is usually 6 or 7.
| Flips | Typical heads | Longest streak (typical) |
|---|---|---|
| 10 | 3 to 7 | 3 to 4 |
| 100 | 40 to 60 | 6 to 7 |
| 1,000 | 470 to 530 | 9 to 11 |
Try it with 100 or 1,000 flips and compare. The percentage gets closer to 50% as the number of flips grows. That's the law of large numbers in action.
Using a coin flip to decide
A coin is perfect for choices where both options are fine: who goes first, which film to watch, where to eat. A useful trick: notice your reaction to the result. If you feel disappointed, you've learned what you actually wanted.
Need three options? Use the 1 or 2 picker and switch to 1, 2 or 3. For a direct answer with “maybe”, try the Yes or No Generator.
