A spider must be guided safely through a maze, eating all the patches of grass. The screen scrolls in four directions, and the walls of the level are in a different pattern on each level, and must always be avoided for fear of losing a life.

As a result, careful planning is required to ensure that you don’t get trapped into a corner. There are seven levels of increasing difficulty to get through.
