Another game more to the list, this played in another forum:
The user that posts makes a deduction on anything of the following in posting (it can be a deduction as random as they want), the follower must post if this is false or true and make a new deduction on the next user example:
"The next one has more posts than me"
The next person has 60 post
and so on
I start, the next person understood what this game is about
