The Escape Effect recently did a tribute to the 25th Anniversary for The 7th Guest. As a result, I broke open the game again and started playing through it with my wife. We got to the microscope puzzle and I quickly remembered how challenging it was. I tried following a bunch of known solutions, but the AI just would not follow the directions indicated by the walkthroughs. Eventually, I came across an online solver that allows players to input which moves the AI is making and gives the player his or her next move. Pretty impressive to analyze and code up such a tool, well done.
On a related note, there’s another online solver for the Stauf portrait puzzle that effectively gets rid of the random element within the game.
