What is a 'Grow Chain' and how do I play?

This is a “closed” game. Balmers invite people they know to grow their StoryNet by dropping a balm on them.

The StoryNet Creator chooses the cause(s) this StoryNet will support. If the Creator chooses only one cause, 100% of the cause dollar from each sale goes to that one cause; two causes, 50 cents goes to each of the two causes; three causes, 33.3 cents goes to each.

It's called a "closed" game only because people who are already in the StoryNet invite others to join by dropping a balm on them.

Anyone can start a new 'Grow Chain' StoryNet, but growing that StoryNet is by invitation.
