Random number between 1 and 100

For a guessing game, a raffle with a hundred tickets or a percentage, the range you want is 1 to 100, and it is already set. Press Generate or the Space bar to pick a number. Each of the 100 numbers, 1 and 100 included, has a 1 in 100 chance, or 1%, on every pick. Picks are independent, so the same number can come up twice in a row.

Uses for a number from 1 to 100

  • Percent rolls. In tabletop games, a number from 1 to 100 works like a d100: a 25% chance means 25 or lower.
  • Raffles. Number up to 100 tickets and pick a winner, or several at once with No repeats.
  • Guess the number. With “higher or lower” hints, you can always find it in 7 guesses or fewer by aiming for the middle: 50, then 25 or 75, and so on.
  • Random samples. Pick 10 or 20 numbers to choose rows, pages or people from a list of 100.

How it works

  1. The range is set

    The lowest and highest numbers for this page are already in the sentence at the top, and both can come up. Nothing to type before your first pick.

  2. Pick your number

    Press Generate or the Space bar, or tap the number. The reel rolls like a slot machine and stops on the result.

  3. Change it if you need to

    Tap how many numbers you want in the sentence to get up to 20 at once; No repeats keeps them all different. Tap either end of the range to type a new one.

1 in 100, or 1%. Every number from 1 to 100 has the same chance on every pick.
