The goal of this game to control a snake to move and collect food (the numbers from 1 to 9) in the screen map. If you collect all the 9 numbers, you win and the game is over. If you try to move the snake with a movement contrary to its movement (eg move it to the right while it is going to the left), you lose and the game is over.

In the same place where a number is eaten, an obstacle is left. If the snake touch one of the obstacles or the edges of the screen, the game is over. To start the game again just write RUN and press RETURN.
