MellowMelon - 2013-02-14 2:48 AM If row e maps to y, and then row y maps to some other row like a, that means a and e are two identical rows in the same grid. Can that ever happen in Sudoku? Oh yea, that's a good logic but I couldn't figure it out  I guess I didn't get the logic of duplicates needing to replace each other. But still it would have been better and more clear if it would have been mentioned in the instructions that 2 rows (duplicates) need to be swapped, no? That's the reason why I didn't get this one solved  I have never encountered a sudoku like this before, so for me it wasn't obvious. | |||

Well, a lot of solving skills depend on the solver's ability to figure out the implied restrictions in addition to the main lettered ones. The rules are just constraints on a puzzle, how they affect the solve is for the solver to see. Figuring out the implied non-literal implications of rules is part of puzzling. For example, now, you'd think the sentence "Place 1-9 in every row, column and box" is enough to describe a classic, but I've come across beginners who still don't figure out for a while that that implies that a number can't repeat. | ||

 Location: India | After linked Classics, Odd Even Big Small was the least submitted/solved puzzles. Here are few steps to get you started. Here is the puzzle.  Step 0 : Figure out that there are no Japanese characters and it must be part of solving to figure out the symbol-property relationship. Step 1 : Note 2 key cells : R7C3 and R7C6. Both of them cannot contain 1 or 4 or 6. Because of that R8C1 and R8C8 cannot be 1 or 4 or 6. A lot of deduction will use this. Step 2 : See the cells in Red. They all belong to one outlined region. Also note that all four of them must satisfy the property of SQUARE. Spoiler: show So clearly SQUARE cannot be Odd or Small (1 is given in the region) It also cannot be Even because 4 does not go anywhere in the Red cells. So SQUARE = Big (5678) You also get R4C1=6 and some more 6s. Spoiler: show Step 3 : Because R6C8=6, you get the 4SQUARES as Even (2468). Spoiler: show Some more deductions (you can first find the red ones, and then the blue ones) Spoiler: show Because of the circle at bottom of C7, we can say circle = Small (1234) and Star = Odd (1357) Spoiler: show | ||
