Talking about indoor games ad a means of teaching and spreading steem around the globe is such a nice idea. But we can consider some outdoor games, we know that most outdoor games hold popularity around the world. Organizing members in the force to form a team say football,tenis, badminton,volleyball etc and naming the various team STEEM will go along way to draw people's knowledge and bring them to light about the existent of steem.
I suggest some popular outdoor games can as well be introduced.
People around my environment loves football but a sponsor has always remain the barrier. If we can achieve a sponsorhip via STEEM this will not only advertise steem but will give them the assurance that they can achieve their goals via steem.
Thats my suggestion sir @dimimp.
