Adjacent numbers (Posted on 2003-01-09) Difficulty: 3 of 5
A : 1
B : 2 C : 3 D : 4
E : 5 F : 6 G : 7
H : 8

Arrange the numbers in the grid above in such a way that no two adjecent cells (horizontally, vertically or diagonally) have consecutive number in them. For example 1 must not be next to 2. (The letters are shown so that you can easily refer to specific individual boxes.)

well, the two numbers in the middle touch all but one square, therefore they must be the numbers one and eight. that means that 2 and 7 must be in the top and bottom squares, the opposite of what their respective counterparts in the middle. then, that means that three must be adjacent to the left or right of the number one in the middle, and on the opposite side must be four. then the 5 and 6 must be on either side of the 8, the 5 on the opposite side from the four.
