WSPC Organizer Posts: 739 Location: India | neerajmehrotra - 2011-06-08 11:59 PM Rohan Rao - 2011-06-08 9:53 PM Any particular reason puzzles of Round 2 are 20x20? I understand the concept is big grids, but was 20 chosen as a random round figure or does it have any significance? Just for trivia sake... 20-20.........WE are heading for sudoku premier league... 20 puzzles in Round1, 20x20 size grids in Round2, 20 puzzles in Round3, I knew something was up! The Nov-2011 WPC in Hungary is the 20th WPC, so thats why. And also because I am 20 years old ;) | ||

WSPC Organizer Posts: 542 Location: India | 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... | ||

Posts: 17 Location: India | okay..is this solution possible for the given 'tiger in the woods' example given in the IB ? | ||

Posts: 81 Location: India | I think the players want to know if the ending cell can be 'anywhere'. There can be another solution then. (TITW.png) Attachments ---------------- TITW.png (5KB - 0 downloads) | ||

Location: India | This is not allowed. The path can stop only near the wall or a black square. Also, the end point must not have visited earlier. | ||

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. | ||

Mean Minis (2020) Author Posts: 774 Location: India | 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. | ||

Mean Minis (2020) Author Posts: 774 Location: India | 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. | ||
