Carefully block off the ghosts by eating the columns and rows of the grid. Once you eat 80% of the grid, you win! If a ghost hits you or even if the ghost hits the column or row that you're eating, you'll lose a life. As a general strategy, don't bite off more than you can chew... literally. Only eat small sections of the grid at a time to keep Pacxon alive and well. If you get too risky and start eating huge chunks, you could wind up losing a life. Although, I do have to admit that it's exciting to see how big a chunk you can eat at a time.
