Flip a Coin Multiple Times
Click Flip Coin as many times as you like — whether that’s 3, 5, 20, 100, or 1,000 flips. The counter below tracks your total flips, your heads/tails split, and your most recent results.
Flips: 0 · Heads: 0 · Tails: 0
Why Flip a Coin More Than Once?
A single flip is enough for most quick decisions, but flipping several times in a row is useful for games with multiple rounds, classroom probability demonstrations, or just watching how randomness behaves over a longer run. Every flip on this page is generated independently and added to the running count above, so you can flip 3 times for a best-of-three call or 100 times to see the split even out.
Flipping a Coin 100 Times
Flip a coin 100 times and you’ll almost never land on exactly 50 heads and 50 tails — small streaks and imbalances are normal in any random sequence. What you will see is the overall split staying close to 50/50, typically within a few percentage points either way. That’s the law of large numbers in action: individual flips are unpredictable, but the average of many flips is not.
Frequently Asked Questions
- How many times should I flip a coin?
- As many times as your decision needs — even one flip is exactly 50/50. The more times you flip, the closer your overall heads-vs-tails split tends to land to an even 50/50, simply because larger sample sizes smooth out short streaks. This tool keeps a running tally so you can watch that happen.
- What’s the probability of flipping 3 heads in a row?
- Each flip is independent with a 1-in-2 chance of heads, so three in a row is 1/2 × 1/2 × 1/2 = 1/8, or 12.5%.
- What’s the probability of flipping heads 100 times in a row?
- Vanishingly small — about 1 in 2^100, a number far larger than the count of atoms in the observable universe. In practice this never happens. Note this doesn’t make any single flip within a streak less than 50/50 — each flip is still independent of the ones before it.
- Does flipping a coin many times change the odds of the next flip?
- No. Every flip is an independent event — the coin has no memory. Even after nine heads in a row, the next flip is still exactly 50/50. Expecting tails to be “due” after a streak of heads is a well-known reasoning error called the gambler’s fallacy.
