The Instructions say:
1. The numbers outside the grid indicate the number of tents in
that row or column.
2. ... each (Big) tent occupies two adjacent squares instead of just
one square.

In the Big Tent example, there is one row and one column that denote the number 3 (meaning 3 tents), but there are only 2 tents in each taking up 3 cells. Therefore, on the Big Tent puzzle, the numbers outside the grid are actually supposed to indicate the number of cells that have tents in that row or column.

I have not done the test yet, but I feel that this instruction and example discrepancy should be clarified or corrected.

Thanks.
