Way too many possibilities.

Yeh, :-(

Okay here's some help:
There is 1 arrow in each corner pointing towards the middle.
There is 4 single squares in the middle all 1 square apart.
And as for the rest of the ones they make a diamond shape in the middle (but broken up diamond)

Thanks for the hints hiaw.

Thank you, Hjaw, for the help!

Not logical.

Thank you!

Thanks.
