Flip one or more coins online, instantly and securely in your browser — heads or tails, decided by a truly random coin toss. Nothing you flip here is ever sent to Brekzy.
A coin flip is a simple way to make a two-way decision by chance: toss a coin, and it lands on one of two sides, heads or tails, with nothing about the outcome decided in advance. People reach for a coin flip specifically because it doesn't favor either option — it's a fast, neutral way to pick between two choices, break a tie, or decide who goes first, without either side having an edge.
This tool doesn't toss a physical coin — there's no camera, no simulated air resistance, no wobble. Instead, it uses your browser's built-in cryptographically secure random number source (the Web Crypto API's crypto.getRandomValues()) to produce a result that's designed to behave like a fair coin: heads and tails are equally likely on every single flip, and the method isn't the predictable kind of randomness ordinary scripts use for things like animations. The result is generated entirely on your device, never on Brekzy's servers.
"Heads" and "tails" are just names for a coin's two faces — heads usually shows a portrait or emblem, tails shows the reverse design or value. Neither side is the "better" outcome; the whole point of a coin flip is that both are equally likely, so whatever you decide ahead of time (heads means one option, tails means the other) is settled fairly once the coin lands. This tool simply reports which of the two outcomes was generated, labeled the same way a physical coin would be.
Flip a coin many times and the overall split between heads and tails trends toward roughly 50/50 as the number of flips grows — that's what a fair coin looks like over a large number of tries. But any small sequence within that larger batch can easily favor one side by chance alone: a run of 10 flips landing 7 heads and 3 tails, for instance, is completely ordinary and doesn't mean anything is wrong with the coin or the method generating it. The larger the batch, the more closely the totals tend to line up with an even split — but no individual flip or short run is required to "balance out" the ones before it.
Each flip this tool generates is produced independently, and a theoretical fair coin has approximately equal — about 50/50 — probability of landing on heads or tails on every individual flip. That independence is the key point: a flip has no "memory" of what came before it, so the coin is never "due" for one side or the other.
This does not mean a short run of flips will contain equal numbers of heads and tails. Getting heads four times in a row, for example, is entirely consistent with a fair, unbiased coin — on the very next flip, heads and tails are still equally likely, exactly as if no flips had happened before it at all. Expecting a streak to "even out" soon is a well-known reasoning error called the gambler's fallacy, and it doesn't describe how independent random events actually behave.
Yes. Every flip is generated using your browser's cryptographically secure random number source (the Web Crypto API's crypto.getRandomValues()), not the ordinary Math.random() function most simple scripts rely on.
Yes. Set "Number of flips" to anywhere from 1 to 1000, and every flip in that batch is generated independently the moment you click Flip Coin.
Yes. A single flip shows a large heads or tails result. A batch of flips shows a heads/tails/total summary with percentages, plus an optional compact list of the individual results.
No. Coin flips happen entirely in your browser and are never sent to or stored by Brekzy. Refresh or leave the page and the results are gone unless you noted them yourself.
Yes. Each flip is an independent event with approximately equal (50/50) probability of heads or tails, regardless of what any previous flip showed.
Randomness doesn't guarantee an even split over a small number of flips — getting heads several times in a row, for example, is entirely normal for a fair coin. The 50/50 split becomes more visible as the number of flips grows, not because the coin "corrects" itself.
No. The outcome is generated first, securely and instantly. The brief spinning animation shown for a single flip is purely cosmetic and plays after the result already exists — it never changes or delays the actual outcome.
