The details are explained this article but a popular bitcoin game, SaruTobi, integrates Counterparty and distributes SaruTobi tokens to those who donated bitcoin to the dev.
It is using IndieSquare’s beta tipping tool to help monetize the app at the same time creating a relationship with its players through Counterparty tokens.
What you can do with the coin is not yet very clear but I’m pretty sure as more players tip. more interesting opportunities for future collaboration and interesting use cases.
Just thought it would be a good idea to share the article in the forum.
