Write Numbers - Back to the Geometry Puzzles
Write the numbers from 1 to 8 into the squares, so that the squares with consecutive numbers do not touch (neither edges nor corners).

I think the trick is that the middle 2 squares touching a lot of squares have to be 1 and 8 since they have only 1 adjacent number which allows you to put more numbers around them... once you start there, the puzzle virtually solves itself...am I making sense?

absolutely correct. since the 2 middle squares touch almost all the other squares, except one each, they need to be 1 and 8. then that means the ones on the left and right need to be 2 and 7 and the ones on the top and bottom are the remaining four numbers. any combination that follows this configuration and the edges/corners rule is a possible solution.

i think u r making sense... but thats me. but i also think what u mean is that the two middle squares are touching all but one other square. and as u said 1 and 8 are the only ones that have 1 other adjacent # . so they therefore are the only #s that can fit into the middle spots. then of course u put the # that is adjacent to those #s in the only spot where each of the two middle spots can't touch
