Giveaways tips

🎁

Number your entries 1 to N, then generate one random number in that range. The entry with that number wins β€” completely fair and auditable.

πŸ’‘

For multiple prizes, use "List" mode with unique enabled. Generate one number per prize β€” no duplicates, so each entry can only win once.

πŸ”

Cryptographically secure randomness means no pattern or bias. Share your range and entry count publicly so participants can verify fairness.

πŸ“‹

Screenshot the result with the range visible to share with your audience. Transparency builds trust in your giveaway process.
