One flip, then you live with it
Flip a coin when the choice is small and you have already agreed to accept either side: who goes first, which trail, which of two equal options. The button asks the browser for a random integer, zero or one, and shows heads or tails. There is no “best of seven” built in. If you flip again because you disliked the answer, you are not flipping a coin. You are stalling. Decide that rule before you press the button.
The count under the button is the flips since this page loaded. Reload clears it. Nothing is sent to a server, and the history is not a record you can audit later. Do not use it for a raffle, a bet, or anything that needs a witness. A shared screen is a better witness than a screenshot of a website. This is a convenience for a low-stakes toss.
Fair means 50/50 on each flip, not a balanced history
Each flip is independent. Five heads in a row does not make the next flip more likely to be tails. The running tally is there so you can see what happened, not so you can “correct” it. If you need many flips for a game, keep pressing. The list shows the latest results, newest first, up to twenty. Older ones drop off the list. The totals still include only what is currently listed after that point, because the list is the history.
A timer is a different kind of decision. If the question is “we start in five minutes,” open the 5 minute timer after the coin has chosen who starts. If the question is a date, the coin will not help. Days between dates and the countdown are for time, not for chance. The stopwatch will not flip a coin either. Keep the tools separate so the toss stays a toss.
- Agree that the first flip counts.
- Heads and tails are equally likely on every press.
- Reload clears the history.
- Do not use this for money, prizes, or anything that needs a paper trail.
What you see is the whole mechanism
The coin on the screen is a picture of the result, not a physics simulation you can bias by timing your click. The result is chosen, then the picture turns. Reduced motion in your system settings does not change the fairness. There is no account and no sound you must enable. If you wanted a random number in a range, or a wheel of names, those tools exist on the French site and are not part of this English set. Here, the question is heads or tails.
