If you video stream giveaways to your participants in real-time, then the Multi-Round Giveaway Service is for you. Paste your list of up to 4,000 participants into our form and select the number of rounds you want, or simply roll the dice for a random number of rounds. Then randomize the rounds one at a time until you have your winner. In the final round, we generate a verification code, valid for one month, which proves your giveaway wasn't rigged.
Whether you run 2 or 2,000 giveaways per month, we have a subscription plan to fit your needs.
All RANDOM.ORG services use true randomness from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.
