This is the last achievement you'll get in Kings Quest. For this achievement, you need to complete all 6 of the puzzles on the Floating Island, which is the last area of the game. The first 2 or 3 are very simple and once you read the note on the table for each you should be able to figure it out. The last 3 or 4 are more difficult and I used a video guide for them. Once I saw them completed, it was easy to see what they were asking me to do. The video is below. All credit goes to
