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.

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

For me the first round points are not added in the commulative result. Any idea how I can get it corrected?
