Infographic signs on the road to game theory understanding

Game Theory Icons

These are pretty clever. I have not walked my way through them yet, but they use arrows to show the relative gradient of payoff for each player, and a little blue circle to represent Nash equilibrium (if any) for the game.

What I have not yet figured out with these is whether or not they can be used to teach the Nash equilibrium for each game… can you use the direction of the arrows to better understand why a Nash equilibrium exists and, if so, why it exists?
