Coin Toss Streak turns a simple heads-or-tails flip into a fast, addictive prediction game. Call the coin before it lands; get it right and your streak grows, get it wrong and you start over. The goal is to build the longest run you can and beat your personal best.
It's free, needs no account, and runs in your browser. Each toss is an independent 50/50 draw, so a long streak is a genuine feat of luck — and bragging rights.
How to play Coin Toss Streak
- Predict whether the next toss will be heads or tails.
- Watch the coin flip and reveal the result.
- A correct call extends your streak; a wrong one resets it.
- Keep going to chase your longest streak and beat your record.
What's the longest streak possible?
There's no fixed limit — in theory a streak can run forever, but the odds make it hard. Each correct call is a 50% chance, so the probability of a long run halves with every step: five in a row is about 1 in 32, ten in a row roughly 1 in 1,024. That steep curve is exactly what makes a long streak so satisfying.
Is the coin fair?
Yes. Every toss is generated independently with an equal chance of heads or tails — the coin has no memory of previous results. A run of five heads doesn't make tails 'due' next; the next toss is still a clean 50/50, which is the heart of the game.
