Weighted random wheel: odds and exclusion rules
A weight is a relative share compared with the other candidates, not a guaranteed win. An entry’s probability is its weight divided by the total weight of currently eligible entries.

Set up a draw1. Set integer weights
Enable weights and enter an integer from 1 to 100 in each entry’s number field. This example uses A=1, B=2 and C=3. Zero and fractional values are invalid. Rules lock after the first draw, so disclose and verify the intended shares beforehand. Equal weights give equal chances.
2. A 1:2:3 probability example
The total weight is 1+2+3=6. A has a 1/6 chance, B 2/6 and C 3/6. A weight of 3 does not mean 3%. One draw cannot establish the distribution, and a small number of draws can differ from expected shares. Percentages below are rounded to two decimal places.
| Entry | Weight | First round | After excluding C |
|---|---|---|---|
| A | 1 | 1/6 (16.67%) | 1/3 (33.33%) |
| B | 2 | 2/6 (33.33%) | 2/3 (66.67%) |
| C | 3 | 3/6 (50%) | Excluded |
3. The next round after excluding C
If exclusion is enabled and C is picked, C leaves the next round’s candidates. The total becomes 1+2=3, giving A 1/3 and B 2/3. Probabilities change even though A and B keep their weights. With exclusion off, C remains eligible, the 1:2:3 ratio stays and an entry can be picked again.
4. Wheel segments and visual effects
Wheel segment sizes reflect candidate weights. Reel, cards and lottery balls use the same weighted rules, but decorative card or ball counts do not represent candidate counts or odds. The result is chosen when the draw begins; animation presents that result. Explain weights and exclusion to participants and keep needed results as CSV. Weights apply to reel, wheel, cards and lottery balls. They set the chance of each draw, without guaranteeing win counts in a small sample. Marble races ignore saved weights.
