# How to define exception rules between participants?

**In Step 1 - Organization**, you can define exclusion rules between participants.

It is very useful to define rules such as "No draw possible in a couple", "No draw possible between brothers and sisters", "No draw possible between people of the same department", etc.  You are free to define the rules you want. 

**You can define:**
- Groups in which people will not be able to draw each other (fastest way)
- Individual exclusions (which you can cumulate with those from the groups)

|| Note 1: a person can never draw their own name. If person A draws person B, B could also draw the name of A (they will only discover this on the day of the gift exchange).  
|| Note 2: Exclusions are not visible by participants.
