- Set all teeth to IN
- Click on the door to the mansion and see how many teeth you have wrong
- Write down 1 - 8 on a piece of paper
- Change tooth 1 to Removed (Out)
- Click on the door again. If the count of teeth you have wrong went down, write Out or Removed beside the #1. If the count of teeth you have wrong went up, write In or Insterted beside the #1.
- Continue on to the next tooth, making sure to set the previous teeth to their correct position. Eventually you will have a key that works.
My pattern was I-I-O-I-O-I-O-I but it seems to change all the time.
