How to Use Weighted Random Choice
Enter one choice per line. Add a comma and a weight when that choice should be more or less likely. Leave the weight off, or leave it blank, to count that line as 1. Click Pick one and copy the label.
Fix any line that the page rejects.
When to Use Weighted Random Choice
Games: Make a common outcome show up more often than a rare one. Workshops: Weight options that the group already prefers. Test data: Bias a label toward the case you need to see more. Menus: Let one dish stay more likely without removing the others.
Why Use This Weighted Random Choice?
A plain random choice treats every line as equal. A weight lets you say how often a label should appear, and a rejected weight keeps a bad line from silently counting as 1.

Before you publish
Unicode styling, formatted code, and converted units can look correct in the preview but fail in the target app because of font support, line breaks, or platform limits.
Test a short sample in the destination (bio field, IDE, CMS, or spreadsheet) before you paste a long block.

Limits to keep in mind
Free browser utilities excel at quick edits, classroom exercises, and copy-paste formatting. They are not a replacement for licensed design software, production build pipelines, or compliance review.
When a platform rejects styled Unicode, fall back to plain ASCII from a case converter or remove formatting before you submit final copy.
Frequently asked questions
What counts as a weight?
A positive number after the last comma. A missing weight counts as 1. Zero, negative numbers, and words are rejected.
Does a higher weight always win?
No. A higher weight is more likely, not guaranteed. Rare, 1 can still be picked next to Common, 100.
Can I use this for a prize draw?
Only for a casual pick. A regulated draw needs a published method and a record you control.
