Gift Exchange Rules
Every 15 minutes, a gift event occurs. The gift event is for one person, starting with the DM, and rotating clockwise.
For a gift event, the person can choose to open an unopened present, or steal an opened present.
The stolen present it marked with a post-it. A present with 3 post-its cannot be stolen.
If a present is stolen from you, now have a gift event as above. You cannot steal back the present you just lost at this time, but can do so later.
note: Some presents are meta-presents which modify these rules.
