Weighted Spin Wheels: Make Some Options More Likely
· 5 min read
Not every decision should be a perfect coin toss. Sometimes one prize is rarer, one option is preferred, or one outcome should be less common. A weighted wheel lets you control the odds precisely — and shows you the exact chances.
What weighted odds mean
By default every option has an equal slice and an equal chance. A weight changes the size of the slice: an option with weight 2 is twice as likely as one with weight 1, and its slice is drawn twice as large, so the picture always matches the real probability.
How to set weights
Turn on weighted odds in settings, then type a weight next to each option. Whole numbers are easiest to reason about (1, 2, 5), but any positive number works. The wheel and the percentages update instantly.
Read the exact probabilities
Each entry shows its live probability as a percentage, so there is no guesswork. This is handy for prize wheels where you want, say, a 5% chance of the grand prize and a 60% chance of "try again."
Combine with no-repeat and elimination
Weights pair well with the other modes. Use no-repeat so a winner steps aside until reset, or elimination to spin down to a single survivor. Together they cover raffles, brackets, and staged draws.
Still provably fair
Weighting the odds does not make the draw less random — the winner is still chosen with a cryptographically secure generator, just with the probabilities you set. Read more on the fairness page.
Frequently asked questions
Do bigger slices actually mean a better chance?
Yes — slice size is proportional to weight, and weight is proportional to probability, so what you see is what you get.
Can I use decimals for weights?
You can use any positive number, but whole numbers are easier to reason about and read at a glance.
