raffle-winner-picker FAQ

Can the same person win twice?

No. The skill prevents duplicates by default. You can exclude previous winners when picking additional winners.

If your data includes an 'entries' column or similar field, you can weight selection so entries with more tickets have proportionally higher chances of winning.

Can I verify the selection was truly random?

Yes. The skill records the timestamp, selection method, and can provide a seed value for third-party verification of the randomness.

What data sources are supported?

Google Sheets, CSV files, Excel spreadsheets, and plain text lists. You can paste data directly or provide file/URL references.

Can I pick multiple winners at once?

Yes. Specify the number of winners needed (e.g., 'Pick 5 random winners') and the skill will select them without duplicates.
