Pick a number between 1 and 30
This wheel has 30 numbers, 1 to 30, each with the same 1 in 30 chance (about 3.3%) on every spin. The segments are small, so the wheel is sized to keep every number readable.
It suits a class of up to 30 students by roll number, a day of the month, a raffle with 30 tickets or any group you have numbered. Spin, read the number, and everyone can see it was fair.
To call every number once, turn on "Retire winners". Each number leaves the wheel as it is picked, so you can work through the whole group in random order.
