Translated from French:

DEFLEKTOR is a logic experiment with a laser. Guide your laser beam in each screen.
Reflectors, refractors, mirrors, absorbers, polarisers and optical fibers are your base. Your precise judgment of the angles and trajectories of your high intensity laser is the only way your beam can be directed to the receiver.
DEFLEKTOR is frustrating, compulsive, incredibly cunning; but above all it's incredibly addictive.

... Probably the most difficult game you will play ..
