Write Numbers - solution

Here's another solution.

strikefiend, the corners of the 4 and 5 are touching.

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...

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

6 4

I guess this is the soultion

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.

1 3

5 7 6 8

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

-- 4 7 --

6 1 5 2

-- 3 8 --

strikefiend,

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

And this one? it looks to mee that there are multiple solutions...

In Littlemisshotpink's solutiom 5 and 4 would be adjacent!

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.
