Why Not Just Pick a Number Yourself?
People are bad at it. When you ask someone for a number from 1 to 100, they tend to skip round numbers and repeats. They lean toward numbers that "feel random", like 37 or 73. That is a human habit, not chance.
A random number 1-100 generator has no favorites. For a prize draw, a turn order or a bet, a tool that does not care about the result is the whole point.
Number Generator 1-100: How the Pick Is Made
Your browser has a built-in source of unpredictable numbers. We use it to draw the number before anything moves on screen.
There is one small trap. A lazy shortcut would make 4 of the 100 numbers slightly less likely than the rest. The gap is about 2 in 100 million, so you would never notice. We remove it anyway. If a draw falls in the uneven leftover, we throw it away and draw again. The result is exactly 1% per number.
Randomizer Number 1 100: What the Odds Look Like
| Question | Answer |
|---|---|
| A given number on one pick | 1% |
| A given number at least once in 100 picks | about 63% |
| Picks needed for a 50% chance of seeing a given number | 69 |
| Picks until a repeat is more likely than not | 13 |
The last row is the birthday paradox. After just 13 picks, there is already a better than even chance that two of them match. If you see the same number twice in a short run, nothing is broken.
Pick a Number 1-100 for Something Useful
Raffles and draws. Number the tickets 1 to 100, then draw. Say the rules before you spin.
Classrooms. Number the class list and call whoever's number comes up.
Guessing games. Have someone else make the secret number, then play higher or lower. The smart way is to halve the range each time: 50, then 25 or 75, and so on. This finds any number in 7 guesses or fewer.
Tabletop games. A d100 roll is just a random number from 1 to 100.
Seats, days and tasks. Number the options, then pick.
Need a smaller range? Try 1 to 10, 1 to 6 or 1 to 4. For your own range, use the random number wheel.
Random Number Picker 1-100: Repeats and Fairness
By default, each pick is separate, so a number can repeat. If you need every number once, as in a 100 ticket raffle, turn on elimination mode. Each winner is then removed from the wheel.
There is no limit on how many times you can use the tool.
