Moscow Puzzle Cup 2016 Author Posts: 234 Location: Russia | greenhorn - 2014-04-04 4:36 PM Hi Riad, I want to ask you, whether all line segments which form the turn (in My Line - puzzle 4) have identical lenghts. In the example they have (number 3 and three ?). Thanks in advance Hi Matus, In each cell with a digit or "?" line turns. Segments comprising this corner have an identical length. In cells without digit or "?" where the line turning angle lengths may be different. | ||

Typed Logic Author Posts: 241 Location: Indonesia | To clarify in puzzle 2 (Minefields), the numbers are treated as empty spaces, right? (And hence a numbered cell in the small grid doesn't have to correspond to a numbered cell in the large grid; it just needs to correspond to an empty cell in the large grid, numbered or not.) Otherwise there's an obvious contradiction. But clarifying... And for puzzles 10 and 11, are the bounds M,N included? Or to be more explicit, take puzzle 10 (Loop Between the Polyominoes): is the maximum allowed grid size 26x26 or 27x27? Edited by chaotic_iak 2014-04-04 7:32 PM | ||

I hope that Prasanna understand it and respond. In Puzzle 10 the three maximum allowed grids are 26 x 26, 25 x 26, 26 x 25. M, N in puzzles 10 and 11 are not related. | ||

In the sense, if the line makes a turn at a cell, should that cell definitely contain a number? I answered a similar question from Matus: In cells without digit or "?" where the line turning angle lengths may be different. But may also be identical. | ||

There are no pentominoes in those directions... In example pentominoes can be only into 4 x 4 area. | ||

There are no pentominoes in those directions... In example pentominoes can be only into 4 x 4 area. Then why does the last column contain 3 at the top when it is not part of the 4x4 area? What is the significance of that 3? | ||

The Astronomer, as is normal vision, can see in (tending to) infinite angles. So the only thing to keep in mind is that there should be X number of visible planets and X number of invisible planets blocked by the visible ones. The angles in the example are just to get a better understanding of the visibility block. | ||

Posts: 35 Location: United States | Just as a formatting note, it would be awesome for puzzles like 3 if the numbers were printed smaller and in a corner so you could write the translation in the box without trying to overwrite the digits. Going well so far, but that will end when I reach the optimizers. :) | ||

Typed Logic Author Posts: 241 Location: Indonesia | In puzzle 4 (Across 4 Grids), might the quadrant with black cells actually be My Line? Like, it's just a regular My Line with some removed squares, and the other quadrant is actually the Diayajilin. | ||

What is the significance of that 3? Just saw this. That 3 would come into play IF you prove that the 4x4 area is inclusive of it. It can also act as counter-proof that it cannot be a part of the 4x4 area. The important part to remember in both cases is you first need to prove where that area is, so the added clues help in restricting that. | ||

Posts: 22 Location: India | I have been participating in your sudoku contests since couple of years and love them. Actually they are the highlights of every month. I have a request please. Could you have the sudoku Classic and Variants contest every month in addition to whatever puzzle contests are on ? The puzzles are quite beyond my ken and almost all of them have to be solved offline which is a bit of a challenge for me. Could you please bring back the monthly online sudoku contests ? | ||

PR 2020 (Shading and Loops) Author Posts: 668 Location: India | A doubt in 10th Puzzle Optimizer. It says maximize the are of rectangle. So does that mean if someone has area 26*26 and other has 25*26 but later one has more empty squares. Does still 26*26 best ? | ||
