This is a game for two players (McBlue owned by Ann and Red King owned by Beth) representing big Sushi restaurant chains. The circles represent towns. The towns are connected by roads as shown. Crossing of roads are bridges and not intersections---you cannot switch roads there.
Build restaurants of your chain in the town by clicking on it. Everybody visits a sushi restaurant once a year if some is in the same city, once every two years if the nearest one is in a neighboring town, and never otherwise. People always go to some nearest restaurant (no matter from which chain). Your task is to maximize the number of customers for your chain, where all towns have the same population in this example. After each click, the colored parts of the towns indicate those people coming to one of the corresponding restaurants this year.
You can alternately place red and blue restaurants. You can change the order with the "red moves" and "blue moves" buttons.
Keep in mind that in the simultaneous game version, since you cannot input both choices simultaneously, this applet is not really for playing, but for seeing the payoffs for various selections. If you want to play the simultaneous version, both players should submit their choice on paper, and then we check the payoff by inputting both moves.
