Coin Flip
A fair 50/50 coin toss with a 3D flip animation and a locally saved history of up to 100 flips.
Quick answer
What is the Coin Flip?
Settle any two-way decision with a fair coin toss. The coin spins in 3D and lands on the result that was already determined, so the outcome is genuinely random rather than chosen by the animation. Every accepted flip updates the running percentages, and the most recent 100 flips are kept in history.
How to Use the Coin Flip
- Tap the Flip Coin button.
- Watch the coin spin and land, then read the result underneath.
- Check the statistics panel for the heads and tails split so far.
- Review the badge row to see the order of the most recent flips.
- Tap Clear to reset your history and statistics.
What You Can Use It For
- Deciding who takes the first turn in a game
- Choosing sides or table position before play starts
- Breaking a tie between two options
- Sports and playground kickoff decisions
- Demonstrating probability and coin-toss fairness in lessons
Tips for Using the Coin Flip
- State the two choices before flipping so the result cannot be reinterpreted afterward.
- Use Clear when starting a new decision instead of mixing separate choices in one history.
- A short streak is normal; use the running percentages to understand longer-term results.
Is an online coin flip actually fair?
Yes. Each flip draws from the browser's random number generator with an exact fifty-fifty split between heads and tails, and no memory of previous flips. A real coin is subject to how it is thrown and caught, which can introduce a slight bias; a digital flip has no such physical influence.
Why do I sometimes see long streaks?
Streaks are a normal feature of random sequences, not a sign of bias. Because every flip is independent, five heads in a row does not make tails more likely on the next flip. The statistics panel makes this easy to observe: over many flips the split converges towards fifty percent even though short runs look lopsided.
Frequently Asked Questions
Is the coin flip fair?
Yes. Every flip is an independent draw with an exact 50/50 chance of heads or tails, with no memory of previous results.
Does the animation decide the result?
No. The outcome is determined first, then the coin is spun to land on that face. The animation is presentation only and cannot change what you get.
Why do I sometimes see long streaks of one side?
Streaks are normal in random sequences. Because each flip is independent, five heads in a row does not make tails more likely next. Over many flips the split converges towards 50 percent.
Is the coin flip history saved?
Yes. Your last 100 flips are kept locally along with running percentages for heads and tails, and you can clear them whenever you like.
