Random Number Generator: Set Any Lowest and Highest: how it works
A random number generator for any range: type a lowest and a highest, and both ends can come up. If all you want is 'give me a random number', one from 1 to 100 is drawn as the page opens. Ask for up to 100 at once, with repeats or without, or tap a ready-made range.
Random number between two limits: both ends count
A range of 1 to 100 holds a hundred numbers, but 0 to 100 holds 101. The line under a single result says so, as '1 of 101 possible numbers'. Minus signs work, and limits run to 999,999,999 either side of zero: -10 to 10 gives 21 values.
For a free prize draw: number the entries, then draw
Give each ticket, name or seat a number and type the last one into Highest: 38 names make this a random number generator 1-38, a hall of 80 seats a random number 1-80. Set How many to the number of prizes and tick No repeats, so nobody wins twice. The share link carries settings, never results, so screenshot a draw that needs proof. A promotion with published rules should use the method its rules name.
Tips
- For a random number 0-1, tap '0 or 1': one bit, heads or tails. Only whole numbers are drawn, so for a decimal set 0 to 99 and read 37 as 0.37.
- Tap '1 to 24' to pick a number 1-24: an hour of the day, or a door on an Advent calendar.
- With repeats on, 1 to 100 will more likely than not show some number twice within 13 picks. That is chance, not a fault.
Questions and answers
Is a number randomizer the same thing as a random number generator?
Yes. Randomizer number, randomizer generator and random number generator are three names for one job. It shuffles too: ask for 30 numbers from 1 to 30 with No repeats ticked, and every item on a numbered list comes up once, shuffled.
Is there a random number picker wheel here?
Not on this page: numbers appear at once, with no spin. When the spin is the point, as in front of a class, type your numbers into Pick for me, one per line, up to 100.
How random are the numbers, and are they safe for passwords?
Each visit starts a small number generator in your browser from a fresh starting point, and every number in your range gets the same chance. Past a few hundred million numbers the chances are close to equal, not exact. That suits games, classes and free draws among friends. It is not built for secrets: never use it for passwords, PINs or draws with money at stake.
