|OCD strikes again!
As you can see from the image above, I managed to get the full score of 207 points in King Tut's Tomb. I owe it all to Adamant, who has been doing a wonderful job of dissecting the code of this game in the comments section of my previous post.
As I had surmised, you lose points if you take too many moves. I had also suspected that the number of matches you finish with influences the score, but it's more insidious than that. To get all of the points, you need to complete the game using just a single match. Given that the torch goes out roughly every 32 moves it seems that this is impossible, but there are some quirks in the code that can be exploited. Simply put, the torch only goes out on move 32 if you have just entered a room (or used the LOOK command). If you do anything else on move 32 (or any multiple of 32), the torch stays lit. By counting my moves carefully, I was able to achieve the screen you see above and satisfy my inner completist.
Obviously this is the sort of thing that can only be done with careful dissection of the code, or an extreme amount of luck. You'd need even more luck than it seems, though, because get this: whenever you light the torch it uses a random number of matches between 1 and 4. I spent more time lighting the torch at the start of the game, checking how many matches had been used, and reloading than I did actually playing. There's also the mummy, who you can't defeat by burning if you want the full score; you just have to rest your hopes on the 50/50 chance that he'll slip on a banana peel rather than kill you. So yeah, the chances of getting this score without knowledge of the code are practically zero, but with Adamant's help I was able to do it. Thanks!
