Winners: Random & Trusted.

RandomPicker helps organizers randomly select winners for contests, giveaways or raffles in a very transparent way. Learn more about our processes, anti-cheating measures and find the guide on how to check if the drawing was fair and unbiased.

How RandomPicker works


The giveaway organizer uploads all participants into RandomPicker.

Random Drawing

RandomPicker generates a unique random number for each entry and assigns prize(s) during the random sorting.

Public Protocol

A public record is generated after each drawing. It proves that the drawing was fair and unbiased. You can check your participation and find all drawing details.

Public Record Guide:
How to check the draw has been conducted correctly and without bias?


Go to the giveaway public record, it’s a unique page generated from RandomPicker. Its address looks like . If you don’t have the link, contact the giveaway organizer, he will provide you with the link.

1. Check the number of entries involved in the drawing and winner(s).

2. Check the anonymized list of entries, look for suspicious duplicates or extreme weights of specific entries. Duplicities can happen if they are allowed by the competition rules.

3. Check previous projects done by the same organizer. Several recent deleted draws with the same name can be also suspicious. Note that test draws are quite common as organizers want to learn how RandomPicker works.

4. Check whether you were involved in the draw using the full-text search. Sometimes organizers import emails, IDs, or other identifiers instead of names. Look at the table of winners to learn what kind of identification is used. The organizer should provide you with your identifier so you can check your participation.
