Thread - Indian Puzzle Championship

rakesh_rai - 2011-06-15 1:55 PM

I was solving the puzzles of Offline finals Round 3. I managed to solve all except NEWS (I tried the small one only, without success) and the big frameless (which I will need to solve on paper). Overall, very nice puzzles. For me, the best of the lot were the polyword (took a lot of time for solving), creek (elegant solution) and digit battleships (nice play with numbers) - the bigger grid in each case.

I hope someone can help with some baby steps for the small grid of NEWS.

Hi Rakesh,

According to me, you are not thinking :-)

1: Look at the R2C5-R3C4-R3C5 region. It cannot have 'W' and 'N'. So 'E' will be in R2C5 and 'S' in R3C4.
2: Exactly similarly, the R4C3-R5C2-R5C3 region will have 'E' in R4C3 and 'S' in R5C2.
3: The square region with 'W' has to have a 'N' in R2C3.
4: The R3C1-R4C1-R4C2 region cannot have 'E' and 'W'. Hence R3C1 is 'N' and R4C1 is 'S'.

You should be able to complete it now.

rakesh_rai Posts: 774 Country : India	rakesh_rai posted @ 2011-06-15 5:31 PM Thanks Rohan. I was actually thinking ...but I had not interpreted the rules correctly (even though this topic was discussed earlier)...I was thinking that a S can come below a W... I thought the only constraints are that W should be to the left of E and N should be above S...but thats not correct...I should be able to solve it now.
