Several coins, one toss
Press the button, and all the coins go up at once. The page starts with four, and you can toss up to ten. When they land, you see how many came up heads and how many tails.
Choose how many
Set How many coins you want. The toss is the same whether you use two or ten.
What people use it for
- Probability lessons: how often do four coins land two heads and two tails? Guess, then try it.
- Board games that need several coins or two-sided dice.
- Decisions in a group: each person has a coin, and the heads go first.
- Yes or no, best of three: when one toss does not feel like enough.
Watch the count
Each coin has a 50 : 50 chance, but one toss rarely shows it. The count keeps adding up, and after a few hundred coins the two totals come close to each other. That is the law of large numbers, and it is the kind of thing that is easier to see than to explain.
Just one coin?
For a single toss, try Flip a Coin, or Heads or Tails when you only need a quick decision.
