WheelJarCan I make some entries more likely than others?
Most wheels treat every slice as equal. Real draws rarely are: someone bought three tickets, someone has not won yet.

How this works
How weights become odds
Each entry’s chance is its weight divided by the total of all weights.
| Entries | Weights | Chance for the first entry |
|---|---|---|
| 2 entries | 1 and 1 | 50% |
| 2 entries | 3 and 1 | 75% |
| 5 entries | 3, 1, 1, 1, 1 | 43% |
| 5 entries | 1, 1, 1, 1, 1 | 20% |
| 10 entries | 5 and nine 1s | 36% |
A weight is not the same as extra slices on the wheel: it is one entry with a larger share of the circle.
Frequently asked questions
How do the odds work out?
Each entry’s chance is its weight divided by the sum of all weights. With Alex at 3 and four others at 1, Alex has 3 in 7, or about 43 percent.
Can I use decimals?
Yes. Weights of 0.5 and 1.5 work exactly as you would expect.
Does an entry with weight zero ever win?
No — zero-weight entries are dropped before the draw rather than given an infinitesimal chance.
