What is Coin Flipper?

A fair, random coin toss whenever you need one. Settle a decision, play a game, or just see what comes up — no real coin needed.

Each flip uses a built-in random source with a 50/50 split, so probabilities match a real coin without the wobble of biased physical tosses. The tool keeps a running history, a heads-vs-tails count, and the current streak — handy for spotting when a session ran abnormally long on one side, or just for double-dare bets.

How to use

1. Click the Flip button to toss the virtual coin
2. Watch the coin animation and see the result — heads or tails
3. View your flip history and running statistics for heads vs. tails

When to use

• Settling a split decision when nobody wants to go first.
• Demonstrating probability and streaks for a school stats lesson.
• Running a fair tiebreaker on a video call where no physical coin is around.

Result

Flip 10 coins in a row — you might get 6 heads and 4 tails, or any other split.

FAQ

Is the coin actually 50/50, and can I make it unfair?

By default every flip is a true 50/50 — a fresh random number maps the bottom half to heads and the top half to tails, with no streak memory. If you want to experiment, open Customize and drag the Heads probability slider to weight the coin (say 70/30 or 90/10); the convergence chart then settles toward whatever odds you set. Leave it at 50% for a perfectly fair toss.

Why am I seeing six heads in a row?

Streaks of six are expected roughly once in every 32 flips. Long runs feel surprising but match the math. The history panel exists so you can verify the totals trend toward 50/50 the longer you go.

Can I flip several coins at once?

Yes. Set Coins per flip to anything from 1 to 100 and a single click tosses all of them. The result panel shows the batch tally (heads vs. tails for that throw) and the running history below adds each coin individually so the streak and overall stats stay accurate.

Does this work offline?

Yes. Once the page is loaded, every flip happens privately on your device. There's no network call per flip, no account, no record sent anywhere. Refresh wipes the history if you want a clean slate.

What's a fair way to use this in a coin-toss bet?

Have one person call heads or tails before the other clicks Flip. Display the result side by side, or share a screen on a call. The history list provides a public record if either party wants to re-check the run.
