Each entry has a weight, and the % column shows its real chance. Change a weight and the slice grows or shrinks to match.
How to set percentages
Type your entries, one per line, then give each a weight in the list under the box. Weights work like shares: 50, 30 and 20 become exactly 50%, 30% and 20%. They do not have to add up to 100; the % column always shows the real chance. Use whole numbers from 1 to 1,000, so for 12.5% use 125 next to 875.
Visible odds, no hidden rigging
On this site a weight always changes the slice size, so the wheel shows the true odds, and a Weighted label appears above it. There is no setting that secretly picks a winner. If you are running a prize wheel, that is exactly what people want to see.
Ideas
- Prize wheels with rare big prizes.
- Game loot tables: common, rare, epic, legendary.
- “Mostly yes” decisions, such as 70% gym, 30% rest day.
- Classroom raffles where extra tickets earn extra weight.
Questions
Can I spin a wheel with adjustable probability?
Yes. Give each entry a weight; the % column shows its exact chance and the slice is drawn at that size.
Do the weights have to add up to 100?
No. Any whole numbers work; each entry’s chance is its weight divided by the total, and the page does the maths for you.
Can I make a rigged wheel?
Not a hidden one. You can set the odds openly with weights, and the wheel will always show them. If one option should always win, there is no need to spin.
Is the percentage exact?
Yes. The pick uses rejection sampling over the total weight, so an entry with 5% wins exactly 5% of the time in the long run.
