### Preptest 16, Sept 2005, Logic Game #3

Anyone figured out how to do that problem? Really tough. Is it an advanced linear or a mapping game. HELP please

first off, that's september 95.

I think this is a medium to easy difficulty game. it's simple to diagram, and there are three options for each house -- it's just asking you to make a couple semi-difficult inferences off the bat that sort of have a cascade effect. For one, Rs always need to touch one or more T, which means 8 can't be R. It also can't be S, because adjacent houses can't match. Since there are only 3 options, you've solved that house, which also allows you to knock out one possibility one the house across from it, because houses can't match across the street, and so on.

This is a pretty common way that pattern-oriented games based on knocking out one of a few possibilities 'work' (the following cars are red, green, or purple; the boxes are full of tools, gears, or machine parts, etc) -- there's a major cascade effect once you make the first big inference, and they're set up in such a way that you can solve about half of the game by following them as far as they'll take you. if you don't make them and try to brute force solve everything, you're generally in for a really rough time.
