In the only order that seems possible for them to be put on.. it looks as if all three are within 6 inches of another tetra
BUT the 2nd red tetra is not placed on top of the first.. which would void it.. and also void the blue tetra.. because it does not look to be within the 6 inches of the only legally capped red tetra
this is a strategical anticapping defense to me.. but no probable to do...
it's similar when you place a tetra on a goal you already own and the tetra falls to one of its previously lower vertices.. and now rests in a position perpendicular to the goal tetra-- the tetra doesn't count.. but it prevents your opponents from placing a tetra on top.. sorry don't have a pic
