Random Wheel with Odds — controlled randomness
A random wheel with odds gives you controlled randomness: outcomes are still random but follow the probability distribution you define.
Useful anywhere you want non-uniform randomness — loot tables, classroom activities, scenario generators, and testing workflows.
Add or rename outcomes in the Inputs panel, set a positive weight for each one, and check the live percentage before spinning. You can disable an outcome temporarily without losing its label or weight.
Controlled randomness, transparent odds
Every entry shows its exact odds so participants always know the probabilities.
Set exact odds
Weights convert to precise percentages shown next to every entry.
Spin & verify
Run many spins and compare results against expected probabilities.
Equal-odds toggle
Equalize in one click for a standard fair spinner.
For raffles, giveaways, and contests where fairness matters, we recommend using a standard equal-probability wheel so every participant has the same chance of winning.
Frequently Asked Questions
- What is the Random Wheel with Odds?
- The Random Wheel with Odds is a free online spinner where you assign custom probability weights to each entry. Higher-weight entries are selected more often, making it ideal for probability education, game design, and scenario testing.
- How do I change the probability of an outcome?
- Edit the weight next to each entry in the Inputs panel. The wheel shows the resulting percentage live. Higher weight equals higher probability.
- Are the probabilities transparent?
- Yes. Every entry displays its exact probability percentage so you always know the true odds before you spin.
- Can I reset to equal odds?
- Yes. Click Equalize to set every entry to the same weight, producing a fair equal-probability spin.
- Is this suitable for a fair raffle?
- Weighted wheels are designed for simulations and games, not fair draws. For raffles and giveaways, use the equal-odds main picker wheel so every participant has the same chance.
