Coin, Dice & Number
Flip, roll, or draw a random number.
Free to use · No sign-up needed
A coin, a handful of dice, and a number in any range
Three of the oldest ways to settle something, on one page. Flip a coin when there are two options. Roll dice when you need a number between one and something small. Draw from a range when you need a number between one and anything at all.
There is nothing to install and no sign-up. Pick the mode you want at the top, press the button, and read the answer. Everything runs inside your browser, so it works on a plane, in a basement, or anywhere the connection drops out after the page has loaded.
How to use it
- Choose Coin, Dice or Number with the buttons at the top.
- For dice, set how many and how many sides. For numbers, set the lowest, the highest and how many to draw.
- Press the big button. The coin spins, dice tumble, numbers appear.
- In coin mode a running tally sits underneath, so you can settle best of three without counting on your fingers.
Good uses
- Two people, one decision: flip for it and stop arguing.
- Board games where the dice went missing years ago.
- Tabletop role-playing, where a twenty-sided die decides whether you survive.
- Classrooms: draw a number to pick a question, a page, or a seat.
- Raffles and prize draws: turn on no repeats and draw as many winning numbers as you need.
About the tally
The coin keeps count of heads and tails until you reset it or close the tab. It is there for best-of-three and best-of-five, and for the moment somebody insists the coin is rigged. Watch the counts drift towards even as the flips add up, which is what fair actually looks like.
Drawing numbers without repeats
Ordinary draws can repeat, the same way rolling a die twice can give you six twice. Turn on no repeats and each number comes out at most once, which is what you want for raffle tickets, seat numbers, or picking a random sample. If the range is too small for the number you asked for, the tool says so rather than quietly giving you fewer results than you expected.
Questions people ask
- Is the coin flip fair?
- Yes. Heads and tails are equally likely on every flip, and previous flips have no effect on the next one. A run of five heads is unusual, not impossible, and it does not make tails more likely afterwards.
- Which dice can I roll?
- Up to six dice at once, with four, six, eight, ten, twelve or twenty sides. Six-sided dice show the familiar pips; the rest show numbers, because nobody can read twenty pips at a glance.
- What does the no-repeats option do?
- It draws without putting numbers back, like pulling raffle tickets out of a hat. Ask for five numbers between one and three and the button switches off, because there are not enough numbers to go round.
- Is anything I do here recorded?
- No. Every flip, roll and draw happens in your browser, and nothing is sent to us or stored anywhere. Closing the tab loses the tally, which is the only thing the tool remembers.
- Can I use this for something that matters?
- For deciding who buys coffee, absolutely. It uses the randomness built into your browser, which is fine for games and fair for settling arguments, but it is not a certified source for gambling or legal draws.
