How to Win Dr. Cockroach's Game on Monsters Vs. Aliens

The Nintendo DS version of "Monsters Vs Aliens," based on the movie of the same name, offers younger players a series of adventure-themed levels featuring the movie's characters. One level features the movie's mad scientist character, Dr Cockroach, as host of a refraction-based puzzle that must be solved before the level can be passed. Solving the puzzle is deceptively simple, but requires careful placement of the mirrors given to you.

Instructions

     Drag a mirror directly under the green circle closest to the switch.

   • 2

     Place a mirror on the square to the left of the switch.

   • 3

     Place the last mirror to the right of the green circle closest to the switch to complete the light's path over all the green circles.
