Other than the first 3 golden squares, this seems next to impossible to actually find anything more

Zone and Marluna are built different (I imagine this comes with a lot of experience).

I mean yeah but they “bifurcated” (picked one of the possible numbers for a square and see if it leads to a solution or a contradiction). If you do it without that it seems next to impossible.

…? How did you only get three?

The one O.kazo has (minus the [5] on R5C8) are the stuff even I can get without bifurcation.

Even if you focus on the fact that each column/row has to have at least one golden square representing the column/row, then you’d still have 4 golden squares minimum. (I.e., R2, C2, C4, and C5.)

#28307

only my last input was a guess. (the [5] in box 6) everything else was “simple” logic.

for example:

the 8 in row 8 is forced in box 7 (bottom left box) (since there is no gold box in row 8 in the other boxes)
similarly in column 8 it is forced in box 6

which forces the [8] in box 9 in the bottom right spot. (the golden numbers can’t be [8] and anything else is eliminated through box 6 and 7)

#28308

Yeah… It’s darn hard, even for me.
One could argue that they could “think forward” (i.e., think several steps ahead in their mind), but I don’t have the mental capacity (or patience) to do that, so I just bifurcate by placing it. (Thank lord for the undo button.)

Maybe I don’t understand the rules then :wowee:

Golden squares is either (A) its column, (B) its row, (C) its place in its box. (So like, R3C1 would be a [7].)

Since all golden squares are given, you’d also have to play with negative constraints. E.g., “Row 2 has to have a [2] and the [2] in Row 2 is a golden square because of (B).”

…actually, I don’t think Marluna plays Sudoku? 'Cuz I haven’t seen her on cookie threads talking about it.

So stupid so useless

#28316

This is all I could figure out. Idk what you mean by negative constraints because I don’t get how the rule implies that.

But basically number x in row x has to be in a golden square?

Or is it number x in row x, column x, or x position in box needs to be in a golden square?
