Once the mechanism has been patched up and the access card is in place, a sequence of four colors must be entered in order for the secret door to open. The name of each color to be entered is displayed in the mechanism window.
The name of the color is written in the second language. The player must first turn the crank until the right color appears in the hole in the gear. Then, to enter his or her selection, the player pulls on the lever located on the right. To hear the name of the color again, the player simply brings the mouse pointer over the word displayed in the window.
