Squares

Four snakes crawl over a grid of dots, drawing lines as they go, and whoever draws the fourth side of a square fills it and scores it. You do not steer a snake move by move; you program it. A snake looks at which sides around its dot already have lines, and the first time it meets a situation it asks you WHICH WAY?. From then on it always goes that way in that situation by itself. Each turn a snake makes up to ten moves by its rules, and answering a new question ends its turn. Each snake can be a player or the computer. The game ends when every snake is going round in circles, when nothing new is drawn for three rounds, or when every square is filled. The most squares wins.

Controls: Use either controller. The stick answers WHICH WAY?, and the stick and a button drive the menus. The keypad is not used.
