Woks (1986)

Emperor Pong hid all the WOKS in the palace strong rooms, and placed members of his elite forces to guard them. You as the people's champion have been chosen to get their WOKS back. There are nine rooms containing the WOKS, unfortunately some rooms have more guards than others, the first three have only one guard in each, the next three have two in each, the last three rooms have three guards in each. The only advantage you have is that the guards are highly disciplined and never change the route of their patrol, you must learn the routes if you have any chance of defeating them.
