NUMBER PATHS
Place numbers into the empty squares so that the grids contain the
numbers 1-16 in a continuous path. The path can move in any direction,
except diagonally and all squares should be travelled.
For example:
5 3 2 5 4 3 2
7 1 6 7 8 1
14 9 15 14 9 10
11 16 13 12 11
Now, solve the following:
6 9
4 1
3 2
15 12
