In the Mine Shaft video mode (the one you get from hitting the inner upper loop shot) I’ve heard that there are some “patterns” that this mode can have as to where things are. Playing it yesterday I found that if I had one where Choice 1: Far Left gave me 10m and Choice 2: Far Right gave me 20m, I could go Far left, Far Left again for 30m or 40m. Didn’t figure out where the 50m was though for the next award.
I have reason to believe that it is correct :-). Consider it “pseudo random”. There are certain elements which are truly random, but their are other elements which are definitely not.
The first and second screen choice (2 doors and 3 doors) are 100% random. Go where you heart takes you.
On the third and fourth screen (4 doors and 5 doors) you will never, and I mean never get the millions on the two right hand doors. I forget whether you can get diamonds there, but I don’t think so.The left side there is still pseudo random, but 100% better than the right hand side!! Around 12.5% of the time, then, you will see left-all-day work perfectly.
Note that this is when the game is in tournament mode. I have no idea if this true in non-tournament situations.
I used to own a Congo and I will concur that left is usually better. Another strange element is how fast you pick them. I know it may be in my head, but sometimes picking the doors really fast would yield all correct guesses.
