During the mid-90s, Philips ported a good chunk of their older CD-i titles to Windows/Mac OS computers. Merlin's Apprentice is no exception.
Puzzle Skip#
Go to the game piece menu. From left to right, top to bottom, click the pieces in the following order; 11, 12, 4, 3, 8, 6, 12, 3, 6, 9, 5, 2, 10, 1, 7. If any mistake is made, the game will have to be restarted. The text at the top will reset to "Select A Game Piece" when entered correctly.
Once activated, puzzles can be instantly completed by moving the cursor to the top-right corner and pressing the Left Mouse Button. On the magic potion screens, using the skip once will gather all ingredients, and a second use completes the potion and starts the next section of the game.
In addition, clicking the flower on the main menu while the puzzle skip is active will show a set of SMPTE color bars.
