How to use Coin Flip
- Choose how many times to flip, from one to one hundred.
- Optionally call Heads or Tails before the draw; leave No call when you only want results.
- Select Flip coin. Read the results in order and the counts, then copy a sequence you need to keep.
Example: Coin Flip
Make a short series of heads-or-tails picks and compare them with a call.
Options
- How many flips
- One run makes 1 to 100 independent two-sided draws. Heads and Tails can repeat; the counts add to the number of flips.
- Your call
- The call is a prediction for comparison. It does not influence the draw, and No call leaves the comparison out.
- Sound and full screen
- Sound is off until you turn it on. Full screen and wake lock depend on browser support and permission; the flip still works without them.

The call and the draw are separate
The browser supplies random values for each flip. Your call is read after the values are drawn to count matches. With three flips, Heads, Heads, Tails is one possible sequence: two Heads, one Tails and two matches if you called Heads. Another run can differ, even with the same form settings.
Questions about Coin Flip
Why did I get Heads several times in a row?
Each flip is independent. A run of the same side can happen without changing the next flip's chance. Use the counts to review a batch, not to predict the next result.
Does my call change the result?
No. Choosing Heads or Tails only adds a match count after the draw. No call simply omits that comparison.
Can I use this as proof of a fair prize draw?
The tool uses the browser's secure random source, but it does not keep an audit record or provide independent certification. Agree on a process and record the result if other people need to verify a draw.
