    How it works

    When you press Flip, your browser's secure random generator (crypto.getRandomValues) decides the side first: it draws a random number and keeps it only if it falls in a range that splits evenly in two, so heads and tails each have exactly a 50% chance. The toss animation then lands on the side that was already decided; it can't change the result. Every coin in a multi-coin flip is drawn on its own. Nothing is sent anywhere — your stats and history stay in this browser.

    How to flip a coin online

    1. Press Flip (or the Space bar) to toss a coin in 3D. It lands on heads or tails.
    2. Read the result. The side appears under the coin and goes into the history and the stats.
    3. Make it a coin flip game. Choose Best of 3, 5 or 7 and keep flipping until one side wins.
    4. Flip several coins by raising Coins, and the page becomes a coin toss simulator for games or probability demos.
    5. Make it yours under Labels & style: rename the sides, pick a gold, silver or violet coin, and set the flip speed from Off to Slow.

    When a coin toss settles it

    A coin is the quickest fair way to choose between two options everyone accepted beforehand:

    • Kick-offs and first turns: who serves or starts. In soccer, the toss winner picks a goal to attack or takes the kick-off (IFAB Law 8).
    • Tie-breaks: two equal candidates, or a tied round in your bracket maker tournament.
    • Two-way choices: rename the sides “Pizza” and “Tacos” and the coin shows the answer.
    • Shared screens: Present (or F) fills a projector or a video call with the coin.

    Best of 3, 5 or 7 explained

    In a best-of series, the first side to win a majority takes it: 2 wins in a best of 3, 3 in a best of 5 and 4 in a best of 7. The scoreboard shows the score after every flip, such as “Heads 2 – 1 Tails”, and Flip pauses once the series is decided, so nobody flips “just one more time”. A best of 3 takes 2 or 3 flips (2.5 on average), a best of 5 takes 3 to 5 (about 4.1) and a best of 7 takes 4 to 7 (about 5.8). Each random coin flip is independent and 50/50, so either side wins the series exactly half the time.

    Coin flip simulator: many coins and stats

    With Coins above 1, this coin flip generator draws every coin on its own and shows how many landed on each side. Stats counts every flip, coin by coin, with percentages, the current streak and each side’s longest streak. Flip 100 coins and exactly 50 heads comes up only about 8% of the time, while 40 to 60 heads happens about 96% of the time. Streaks run longer than most people expect: in 100 flips, a run of 6 or more of the same side turns up about 81% of the time. History keeps your last 200 flips; Copy gives a sequence like “H T T H”, and Download CSV saves each flip’s time, result, coins, heads, tails and series.

    Is a virtual coin flip fair?

    Yes. This coin flipper decides every flip with your browser’s secure random generator (crypto.getRandomValues) before the animation starts, using rejection sampling so heads and tails each have exactly a 50% chance. Real coins are close but not perfect: in a 2023 study of 350,757 coin flips, František Bartoš and colleagues found that a tossed coin lands on the side it started on about 50.8% of the time, while heads and tails each still came up 50.0%. Nothing you do on this page changes the chance, and nothing is uploaded.

    Flipping a real coin fairly

    Hide which side is up before you flip the coin, and let someone else call it while it’s in the air. Catch the coin or let it land, and never re-flip a result you don’t like. In the same study, the same-side bias came from wobbly flips and shrank as people practiced.

    Coin flipper or yes/no wheel?

    Pick a classic heads or tails coin flip when the two options are equal. Use the yes or no wheel when the question is literally yes or no, or when you would like a Maybe. For more than two options, spin the wheel spinner or draw from a hat with the random name picker; for numbers, try the dice roller or the random number generator.

    FAQ

    Is this coin flip really 50/50?

    Yes. Each flip comes from your browser's cryptographic random number generator, which gives heads and tails exactly the same chance, and the side is decided before the toss starts. Runs still happen: in 20 flips, four or more of the same side in a row shows up about 77% of the time. That is normal randomness, not a bias.

    Can I flip a coin best of 3?

    Yes. Choose Best of 3, 5 or 7 above the Flip button. The scoreboard keeps count, and the series ends as soon as one side reaches 2, 3 or 4 wins, with a banner such as “HEADS wins the series 3–1”. Press New series to start again; the B key cycles through the modes.

    Can I flip more than one coin at once?

    Yes. Set Coins to any number from 1 to 100. Up to 10 coins toss together in 3D; from 11 coins you see a grid of small faces. The result shows the totals, for example “Heads 13 · Tails 7 (65% Heads)”, and every coin counts toward your stats. Best-of series use one coin.

    Can I rename heads and tails?

    Yes. Open Labels & style and type up to 20 characters for each side, such as Pizza and Tacos. The names appear on the coin, in the result, the stats and the history; sides that start alike get distinct initials, like PI and PA. Reset labels brings back Heads and Tails.

    Is a virtual coin fairer than a real coin?

    Usually, yes. In a study of 350,757 real coin flips, a tossed coin landed on the side it started on about 50.8% of the time because of the way people flip, although heads and tails each came up 50.0% overall. A flip-a-coin generator has no starting side and no thumb; every flip here is an independent 50/50 draw.

    Why do they flip a coin before a football or soccer game?

    Because a coin toss gives both teams the same chance at the first choice. In soccer, the team that wins the toss decides which goal to attack in the first half or takes the kick-off, and the other team gets the remaining option (Law 8 of the IFAB Laws of the Game). Other sports use their own toss rules.

    Can an online coin flip be rigged?

    Not this one. A rigged coin flip needs a weighted side, and this page has none: the result comes from your device's secure random generator, not our server. The How it works panel under the coin explains the method, and the stats show the running share of heads and tails, so anyone can watch it even out.

    Can I flip a coin on a video call or in a group chat?

    Yes. Share your screen in the call and press F for Present mode, so everyone watches the same coin land. The Share link carries your settings, such as the labels and best of 3, not a result: whoever opens it flips their own coin.
