How does duplicate prevention work?
When enabled, numbers that have already appeared will not appear again in later draws.
How do I enter excluded numbers?
Use commas for individual values, such as 3, 7, 10. Use 10~20 to exclude a range.
Can I use it for official drawings?
It is fine for casual random selection and simple events. For legally binding or auditable drawings, use a certified system.
