pt 21 logic game 4

Postby burtonrideclub » Tue Apr 06, 2010 10:50 pm

Having real difficulty with this game, maybe my heads just not in it today but I can't seem to make any good deductions. Why does J have to go 2nd? (according to the answer to number 20) Thanks for the help

This game is pretty challenging, i'll try and help you out.

Okay so we got an advanced linear game. Set up a base of 1-4 with two dashes for each.

Rules:
1) HJ block
2) if G --> then GO block or GJ block
3) K is either week 1 or week 2
4) O is week 3
5) the product that is advertised twice appear in weeks 1/2 and 4

Additionally, J can't be in 1 and H can't be in 4, due to the HJ block

Solving #20:
The HJ block only has 3 places you can put it, 1-2, 2-3, and 3-4. If you put it at 1-2, it is okay, if you try and put it in 2-3 means that J is with O, and because G needs to be with one of either J or O in order to be placed, it can't be placed. Therefore HJ can't be put in 2-3. If you try and put it in 3-4, you end up with H with O in 4, and J with blank in 5. However, G needs to be with either J or O, and since O is taken by H, G has to be in 4 with J. However, J can't be repeated, because only 1 product is repeated, and if J is repeated, H must be repeated as well, therefore G must be repeated. However, G can only be with J, which can't be repeated for already discussed reasons, and O, which can't be repeated because it is advertised in 3, and a rule states that the product that is advertised twice appears in weeks 1/2 and 4 (so can't be 3). So therefore, the HJ block can only be placed in 1-2, and therefore J must be in 2.

Hope this helps, please let me know if you can't understand that and I can try and explain it better.
