How to use the Weighted Random Picker
Give each option a custom chance of winning. The controls and result are provided on one page so the task can be completed without an account or uploading the input.
When and why to use it
Use it when options should have intentionally different probabilities, such as a prize table or weighted task rotation.
Example
Enter Common | 70, Rare | 25, and Legendary | 5 to model a 70/25/5 draw.
Step-by-step instructions
- 1
Enter one option per line as Option | weight, then review the displayed probabilities.
- 2
Select Spin and wait for the wheel to finish before reading the announced result.
- 3
Check the result, then copy, print, or export it only if it is suitable for your purpose.
How randomness and fairness work
The browser draws from the total of all positive weights. An option's probability equals its weight divided by that total; larger weights deliberately receive a larger chance.
Limitations
Weights are relative rather than percentages; incorrect weights produce an incorrect probability model.
Questions about the Weighted Random Picker
Is the Weighted Random Picker free to use?
Yes. It can be used without an account or payment, and generation takes place in your browser.
Can I rely on every Weighted Random Picker result?
Treat the output as a neutral generated result, not professional advice or independent verification. Weights are relative rather than percentages; incorrect weights produce an incorrect probability model.
