perplexus.info :: Logic : Six Squared

Six Squared (Posted on 2008-01-03)

	A	B	C	D	E	F
1		44	44		66
2	33		52			49
3	96				57
4	11	6				42
5	67					12
6	4	48	71	62	98	38

Place the numbers 1 to 36 in the 6x6 grid, in such a way that consecutive numbers cannot be adjacent in any direction (including diagonally), nor can they appear in the same row or column.
Additionally, cells which are diametrically opposite have a difference of +/- 18.
So, for example, if number 2 was in cell 1A then number 20 would be in cell 6F; if it was in 2C then 20 would be in 5D.

The small digits show the sum of the figures in the adjoining horizontal and vertical cells.

The large digits (6 and 12) are starters.

This is similar in principle to X Marks the Spot
