Random number picker with no repeats Random number 1-20
Twenty is a handy size
Twenty fits a lot of everyday lists: a spelling list of 20 words, a class of 20 students, the 20 questions at the end of a chapter, the 20 kids on a sports roster. When you need to pick one of them, a number from 1 to 20 does the job, and every number has the same 5 percent chance.
With Keep drawn numbers out of later draws off, as this page starts, each press is independent. The same number can show up twice in a row, just as a twenty-sided die can roll two 17s. Switch it on when you want to work through the list, for instance to hear each of 20 spelling words once in a random order before any word repeats.
Several numbers at once also work. Set How many to 4 to give four students a turn at the board, or to 5 to choose the five questions for a quiz. They are all different, since No repeats is switched on, and Sort from smallest lays them out in order so you can find them in a list.

Getting a number between 1 and 20
- Tap Draw. The number appears in large type, and the next press gives a new one.
- Need more than one? Raise How many. For a whole spelling list in random order, set it to 20 and draw once.
- Switch on Keep drawn numbers out of later draws to call each number only once. The line under it shows how many are left, and Start over puts them all back.
- Use Copy to take the numbers into a document, or Present to show them on a classroom screen.

Questions about numbers from 1 to 20
Is 20 included in the draw?
Yes, 1 and 20 are both possible, so there are twenty results. None of them is more likely than the others.
How do I give every student a turn without repeats?
Make the range match your class size with To, switch on Keep drawn numbers out of later draws and press Draw once for each student. When all numbers are gone the page tells you, and Start over begins a new round.
Can it replace a twenty-sided die?
For a quick roll, yes. It draws from 1 to 20 with equal odds, the same as a fair d20. Table games that ask for a modifier need you to add it yourself.
Can I get a different range?
Change From and To. Any whole numbers work, negative ones too, so 0 to 9 or 1 to 500 are just as easy.
Is my draw stored?
The history on the page stays in your browser only. Nothing is sent to a server, so a fresh visit on another device starts blank.
