“Heads or tails? Let luck decide!”
Flip a coin online, free and fair. Every toss is a true 50/50, powered by a secure random generator. Settle a bet, make a call, or test your luck — flip one or a whole batch and watch your streaks build. Nothing saved, nothing shared.
Tap the coin or press Flip to toss.
A fair coin flip has exactly two equally likely outcomes: heads or tails. Each has a 50% chance — a probability of 0.5, or 1 in 2. There is no third option and no hidden weighting.
Every flip is independent. Previous results have no effect on the next toss. If you flip five heads in a row, tails is not “due” — the odds on the sixth flip are still exactly 50/50. Believing otherwise is a common mistake known as the gambler’s fallacy.
Runs are less likely the longer they get. Two heads in a row is a 25% chance (0.5 × 0.5), three in a row is 12.5%, and ten in a row is under 0.1%. That is why a long streak feels remarkable — it genuinely is.
Over many flips, results even out. Flip a coin 10 times and you might well get 7 heads. Flip it 100 times and you will usually land much closer to 50%. This is the law of large numbers, and you can watch it happen: set the flip count to 100, press Flip, and see the heads and tails percentages settle toward even.
A coin toss is the fastest fair way to choose between two options. People use My Flipping Luck to:
Yes. Each flip uses your browser’s secure random generator for a fair, unbiased 50/50 result.
Yes — it uses cryptographically secure randomness (crypto.getRandomValues), not a predictable pattern, so heads and tails are equally likely every time.
Yes. Do a single flip, or run a batch and see the running tally of heads vs tails plus your streaks.
No. It’s a fair, random flip — great for settling decisions or games, but no tool can predict a coin toss.
Yes. Everything runs in your browser. Nothing is saved, sent, or shared.
Enter 100 in the “Number of coins flipping on each flip” box and press Flip. You will get the full run of results as heads and tails chips, plus a tally, percentages, and your longest streak.
With a real coin it is possible but extremely rare, and it usually needs a rough or uneven surface to come to rest. My Flipping Luck always returns heads or tails, so you always get a clear, usable result.
Very close, but not perfectly. Research on physical coin tosses suggests a tiny bias toward the side that was facing up when the coin was flipped, caused by the way a real coin wobbles in the air. A digital flip using secure randomness avoids that physical bias completely.
Yes to both. It is completely free with no sign-up and nothing to download or install, and it works in any modern browser on phone, tablet or desktop.
