Well yea, you are probably right. Next time I encounter this linked classics sudoku I know better for sure ;)

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.

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.



Step 3 :
Because R6C8=6, you get the 4SQUARES as Even (2468).


Some more deductions (you can first find the red ones, and then the blue ones)


Because of the circle at bottom of C7, we can say circle = Small (1234) and Star = Odd (1357)
