Where are we beginning ??

Finally! Jobar13, start in the top left corner and match the 2's and 3's in the columns and rows - hope that helps - you're looking for a distinct pattern diagnally accross the block down to the bottom right corner...

I just can't get it to work. There are so many possible answers but what's the right one?!

I found two ''correct'' in that they match the numbers. Any more clues possible?

My result is correct, but not the right one.. also, what I have is nice ;)

I keep coming back to this, trying to do it with fresh eyes. I try to follow the clue but always end up doing it wrong. Anyone who solved it have anymore hints to give?

Spoiler:

Diagonally symmetrical. It's a chain with 1 partial link, 2 full links, 1 partial link from top left to bottom right.
Squares on the diagonal all except
1,1 8,8 9,9 16,16 17,17 24,24 25,25
Then each 1,2,3 group forms the end of a link
The first is R1,C3 R2,C2/3 R3 C1/2/3
The second is R6, C6/7/8 R7,C6/7 R8,C6
Reflect that down for each group then join the ends to make a chain.
Hope that helps :-)

That definitely did help! Thank you so much Sparrow :D.

Nice.

Again bad design and thx Sparrow for help.

Thank you for the hint Sparrow. Multiple possible solutions.

Really great hints. Thank you Sparrow.
