Pac-Xon is a fun and addictive game where you need to build walls in order to fill empty space with blocks. But you need to avoid the moving ghosts from touching the Pacman or else you lose a life. Also, the ghosts should not touch the wall while it is being built by the Pacman or else you lose a life and the wall is also destroyed. However, you can trap a ghost by building a wall around him. Keep your eyes open for the fruits that appear on screen.
