Random Number Wheel 1 to 10
This wheel picks a random number from 1 to 10, with every number holding exactly one tenth of the wheel and the winner drawn by a cryptographically secure generator.
Ten slices, numbered one through ten, each holding exactly a tenth of the wheel.
One to ten is the range people reach for most, probably because it maps onto how we already think — pick a number between one and ten is a phrase most of us have said out loud. It settles who goes first, who gets the last slice, and which of ten options wins, without anybody having to justify a choice.
Teachers use it constantly for mental maths. Spin twice and multiply. Spin twice and find the difference. Spin once for the number of jumping jacks, which for some reason lands better than choosing a number yourself. The spin adds a second of suspense and that second is what keeps a class watching.
If you need a wider span, the random number wheel takes any minimum and maximum you set. Above about a hundred slices a wheel stops being readable, and a range picker is the better tool.
Random Number Wheel 1 to 10 — questions
Are all ten numbers equally likely?
Yes. Each number occupies exactly one tenth of the wheel and the winner is drawn with crypto.getRandomValues() before the animation starts, so every number has a one-in-ten chance on every spin.
Can I stop the same number coming up twice?
Turn on "Remove winner after spin". Each number leaves the wheel once drawn, so ten spins give you all ten numbers in a random order with no repeats.
What if I need a bigger range?
Use the random number wheel, which takes any minimum and maximum. Past roughly a hundred slices the labels become too small to read, which is why very wide ranges are handled there rather than here.
