A Magnum Opus
TENTS puzzle consists of a square or rectangular array of squares in which some of the squares
contain a tree, with the remainder containing only grass. The puzzle is solved by placing tents into selected grassy squares so that each tree has its own tent
(either horizontally or vertically), and each tent has its own tree (either horizontally or vertically). The squares in which tents are placed must not touch
on either the sides or the corners. Numbers located to the side and to the bottom of the puzzle tell you how many tents are in each row and column.
Solving the puzzle is a point and click mouse operation. A single click inside a square will insert a black dot in the center of the
square. Insert these black dots into all squares which you know cannot contain a tent. A second click will replace the black dot with a tent, and a third click
will return the square to a grass only condition for those cases where you believe you have made a mistake.
