Ways to use this list
- Decide who kicks off or serves first: one captain calls heads or tails, then spin on the big screen so both teams see the result together.
- Play best of three when one flip feels too quick: pick ๐ฅ Best of 3 under the button, and the side that lands twice wins.
- Maths lesson on chance: with the Two coins button, ask pupils whether "one of each" or "two heads" will come up more, then spin 20 times and tally.
- Streak hunt: flip 30 times and write down the longest run of the same side. Runs of four or five in a row turn up far more often than most people expect.
- Choose between two plans: type them in place of Heads and Tails, such as "Park" and "Cinema", so the wheel shows the answer itself.
Press Spin the wheel, tap the game or press the Space bar. Change the list in the box as you
like: add your own, delete what doesn't suit you, or write *2 after an entry to give it double the
chance. The game buttons switch the same list to a duck race, hat, claw machine and more.

Questions people ask
Is a coin flip really 50/50?
On this wheel, exactly: Heads and Tails each have half the chance, chosen by your browser's secure random generator. With a real coin, a large study of over 350,000 tosses found it lands on the side that started facing up about 51% of the time, so a real flip is very close to fair, but not quite.
What are the rules of heads or tails?
One person calls "heads" or "tails" before the result, and the call wins if it matches. Agree first whether it is a single flip or best of three, and who calls: usually the person who isn't flipping. That way nobody can ask for a re-flip after seeing the answer.
After five heads in a row, is tails more likely?
No. Every flip is independent, so the sixth is still exactly 50/50. A coin, or this wheel, has no memory of past results; the feeling that tails is "due" is one of the most common tricks the mind plays with chance.
Why is it called heads or tails?
Coins have long shown a ruler's head on one side, which became "heads"; "tails" simply means the other side. The game itself is ancient: in Roman times it was called "heads or ships", after the pictures on the coins of the day.
What are the chances with two or three coins?
With two coins there are four equal outcomes, so two heads has a 1 in 4 chance and one of each has 2 in 4. With three coins there are eight, so three heads is 1 in 8. The Two coins and Three coins buttons put every outcome on the wheel.
