Posts: 542 ![]() ![]() ![]() Country : India | rajeshk posted @ 2011-06-09 6:03 PM Tiger in the Woods One rule I wanted to confirm that, can the ending square be in the middle or it should always be touching a wall? e.g. attaching the puzzles from Brazil Puzzle Championship where ending square is not touching the wall or black square. See the following answer booklet https://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=12... |

Cant even figure how to start the sample puzzle Can anyone throw some light? (i know its too late,yet just an attempt) Thanks anyway. All the best everyone ![]() Look at all rows and coloumns with A and B as clues..... means R1, R2, C2, C4 C cannot be placed in 1 and last cells of these rows and columns... with this C cannot be placed in R1C1, R1C4, R2C1, R2C4 therefore in first two rows C has to be in second and third column. Again with the same logic C cannot be placed at R1C2, thus place C at R1C3 & R2C2..... Now its simple. |

Posts: 774 ![]() ![]() ![]() ![]() ![]() ![]() Country : India | rakesh_rai posted @ 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. |

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. |
