Question about this move??

Why doesn't 2 go between 1 and 5 on the middle up side, it can't go anywhere else there because of the 2's below.

I mean like I'm not seeing any mistake there.

Tried like 3 times putting 2 there, but got a "invalid" sound for it -.-

I guess you've excluded the middle column for that square, because there is 2 placed in the bottom. Actually, that lower 2 is located in the square that belongs only to the lower right grid.

Here's a screenshot of another layout, but it should make a good example of overlapping grid usage: http://images.akamai.steamusercontent.com/ugc/440604528669343603/1364CD45865CBA45D06F6ACA5D089C73FAB392F9/

Aah that makes more sense. In previous puzzles I considered that it doesn't overlap, still 9 squares long but it starts like again after 3 squares. like 123/456/789/123/456, I mean it could work like that, and there were no darker borders for it.
