This game is pretty simple. You think of a rule (e.g. first letter has to start with the first letter of username) and pick an item that fits that rule. You say “I started a picnic, and I brought a (item)”. For the example shown, I could bring a dog, because dog starts with the same letter as Dbiz. You do not share your rule with anybody. People respond to your post by saying “I went to your picnic, and I brought a (item)”. If the item fits the rule, op responds with “You can go to my picnic”. If not, say “You cannot go to my picnic”. After 2-3 people make a guess to go to the picnic, the person who started the picnic shares another item that they brought that fits the rule. Once you are allowed to go to the picnic, you can make a guess as to what the rule is. If you guess correctly, then that game ends and you get to start your own picnic.
