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 thought I had a different solution but upon further analysis it didn't work...

False alarm

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

There is actually only one answer to this problem, but there appears to be four. Because the design is symmetrical across 2 axis, the answer can be mirrored to create what appears to be an additional 3 answers.

I am new at this. Could this be another solution?

1 3

5 7 6 8

2 4

No - the 7 and 6 are adjacent. No consecutive numbers can touch. The only solution *must* have 1 and 8 in the center.

Here's another solution.

-- 4 7 --

6 1 5 2

-- 3 8 --

strikefiend,

That is not correct .... 4 and 5 shared a point (meet through the diagonal).

Here is the only one solution mirrored on 2 axis.

That is correct, 8 and 1 should be in the center since they're the only two numbers with one adjacent number (1->2 and 8->7). This makes that between 1 and 2 the 8 is, and between 7 and 8 the 1 is. 4 numbers left, those are the easy pick. Solved this in less then a minute.
