The rules for this category would be simple,

1. No Trading Items or Coins
2. No Auction House (this could be removed because someone "having a good deal" might be someone on an alt providing a good deal).
3. No Jerry's Island or Gifts (So It's not a total RNG fest)
4. No picking up items from other players. (If you pick up an item from another player, you have to throw it out of your inventory)
5. No buying Booster Cookies and selling them for free coins. Feel free to add more rules if you so think they are needed.
