Coin Flip
Heads or tails — flip a truly random virtual coin.
How to Flip a Virtual Coin
- Click "Flip Coin" to flip a virtual coin — the coin animates and lands on heads or tails.
- Check the result message and the growing history of chips below the coin.
- Watch the Heads, Tails, and Total Flips counters update after every flip.
- Click "Clear History" to reset the coin, counters, and flip log back to zero.
Frequently Asked Questions
How is the coin flip result determined?
The tool uses your browser's crypto.getRandomValues() API to generate a cryptographically secure random bit, then checks if it's even or odd to decide heads or tails — giving each side a genuinely equal 50/50 chance.
How many past flips does the history show?
The flip history keeps your 20 most recent results as chips, with the newest flip added to the front; older flips beyond 20 drop from the display, though the Heads, Tails, and Total counters keep counting every flip since the last reset.
Why did I get heads or tails several times in a row?
Streaks are a normal part of true randomness — with a fair 50/50 coin, getting the same result multiple times in a row is expected to happen periodically over many flips, and it doesn't mean the tool is biased.
Does Clear History affect anything besides the display?
Clearing resets the coin face back to its default icon, empties the flip history chips, and zeroes out the Heads, Tails, and Total counters — it's a full reset with no saved data left behind.
Can I use this to make a real decision, like settling a bet?
Yes — since each flip is generated with a cryptographically secure random source, it's as fair as a physical coin flip for casual decision-making.
