Weighted Random Picker — custom probability distributions
The Weighted Random Picker is the same transparent weighted wheel focused on picking named outcomes with custom probabilities.
Use it whenever you want a random pick that is not uniformly distributed — RPG events, software testing, creative prompts, and more.
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.
Custom distributions for any use case
Uniform random is not always what you need — set exact probabilities to match your scenario.
Any distribution
Set weights to match any probability distribution you need.
Named outcomes
Label each outcome for clear, readable results.
Save & share
Bookmark or share your weighted configuration with a URL.
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 Weighted Random Picker?
- The Weighted Random Picker 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.
