The rules:

- The number of tents in the camp is equal to the number of trees.
- Each tent must be located next to "its"
tree horizontally or vertically, but not diagonally. If this
condition is met, location in relation to "foreign" trees
doesn't matter
- Two tents cannot be located side by side, including
diagonals.
- The number of tents in a row or column of the net is determined
the number next to the corresponding row or column.
