A random number between 1 and 70
This page is a random number generator 1-70: seventy equal slices on a wheel, one spin and one number. Use it to pick a number between 1 and 70 for a prize draw, a big group, a long list or a game that needs a wide range without going all the way to a hundred.
It is free, runs in your browser and needs no account. The wheel opens ready on 1 to 70, so you can press Spin and a window shows your number.
How to pick a number 1 through 70
- Decide what the numbers mean. Tickets, people, rows, questions or pages.
- Press Spin. You can also click the wheel or press Ctrl (⌘ on a Mac) plus Enter.
- Read the result in the window. The Results tab lists every number from your visit, newest first.
- Draw several winners by switching on No repeats. Each picked number comes off the wheel until you put them back.
Odds on a seventy-number wheel
Each number has a one-in-seventy chance, about 1.4%, on every spin. Your browser’s secure random number generator picks the number first, and the wheel is then steered to stop on it. The animation shows the result arriving and never changes it. For more detail, see how WheelSpinny picks.
A repeat comes sooner than most people expect. With No repeats off, the chance that a number has come up twice reaches one in two after only eleven spins. This is a standard result in probability, often called the birthday problem, and it is why a draw that must not repeat should have No repeats switched on.
Draw winners from seventy tickets
Seventy is a comfortable size for a school fair, a club night or a community raffle. Number the tickets, switch on No repeats, and spin once for each prize. A ticket that has won comes off the wheel, so it cannot win twice.
Show the wheel on a shared screen so everyone can watch. Say what happens before you begin: how many prizes there are, what order they are drawn in, and what happens if a winner is not present. Copy on the Results tab gives the winning numbers in the order drawn.

Guessing games up to seventy
A guessing game with seventy numbers is long enough to reward strategy. A random guess is right one time in seventy. A player who always guesses the middle of what remains can find any number in seven guesses or fewer, because seven halvings cover up to 128 numbers.
To play, one person spins and keeps the number secret. The others guess in turn, and the spinner answers “higher” or “lower”. Count the guesses and see who finds the number in the fewest.
Other ways to pick from seventy
If you want a log of winners with names, use the raffle generator. To put names on the wheel, use the random name picker. To shuffle a long list in one click, use the list randomizer. Need a different size? Try 1 to 60 or 1 to 75.
You can change the range on this page by editing From and To, or open the general random number generator to count in steps or leave numbers out.
Why a seventy-number wheel needs the text results
With seventy slices on a phone screen, each slice is only a few degrees wide. The wheel is still useful for the show of the spin, but the answer does not depend on reading a slice. The result window names the number in large text, it is announced to screen readers, and the Results tab keeps a plain list that you can copy.
That plain list is also what you hand to other people. If you are running a draw for a group, paste the Results tab into a message so that everyone can see the same numbers in the same order. It turns a quick spin into a record that anyone can check later.
If you want to try a different size for the same job, step down to 1 to 60 or up to 1 to 80. The odds are equal across every number on any of them.
