This maze appears on the first and second rounds. It contains 220 pellets (224 if you count the power pellets).
There are two sets of tunnels in this maze, equidistant from the middle of the maze.
The most dangerous section of maze is the long path at the very top. It is safest to clear it when the ghosts are blue, or at least 3 of them occupy the bottom half of the maze.
Light Blue Maze
This maze appears on the third, fourth and fifth rounds. It contains 246 pellets (250 if you count the power pellets).
There are two sets of tunnels on this stage; one set in the lower half, and the other set at the very top of the maze.
There are a couple of dangerous sections in this maze. The pathways above and below the T section at the top of the stage can be particularly easy to get trapped in. It is easiest to clear these when all 4 ghosts are close on your tail, or after eating one of the top two power pellets. The two sections directly above the lower escape tunnels on either side should also be cleared with caution.
Orange Maze
This maze appears on the sixth, seventh, eighth and ninth rounds. It contains 230 pellets (234 if you count the power pellets).
Unlike all the other mazes, there is only one set of tunnels in this maze, slightly above the center of the board.
The most dangerous section of this maze is the center of the bottom, directly below where you begin. It is advisable to clear it out as early as possible before the ghosts can organize and trap you. The top section of the maze presents the ghosts with many pathways to reach you, so use caution.
It is possible to hang out in front of the left tunnel entrance (facing up), and remain completely safe from the ghosts for a short period. If the ghosts are moving in a clockwise direction, they will be unable to reach Ms. Pac-Man until they are instructed to double back and move in a different direction. At that time, Ms. Pac-Man can safely pass through the tunnel.
Dark Blue Maze
This maze appears on the tenth, eleventh, twelfth and thirteenth rounds. It contains 236 pellets (240 if you count the power pellets).
There are two sets of tunnels on this stage, directly next to each other in the middle of the maze. The turns at the entrance to the tunnels change the usual immediate accessibility of the tunnels and should be taken in to account.
The most dangerous section of this maze is the section that you begin in, and the section directly above the ghost pen. The very top section of the maze should also be cleared with caution.
