Eat up all the dots while avoiding ghosts from getting to you. There are multiple big dots you can eat that will allow you to temporarily destroy any ghosts you eat. Collect the bonus pick-ups to get a score boost.
Use your keyboards arrow keys to move through the maze, while eating the dots along the way. There is a portal that teleports you from the one side of the game to the other to help you get away from ghosts and collect more dots. Don't lose all your lives or else its game over.
