You have a grid of squares, some of which contain trees. Your aim is to place tents in some of the remaining squares, in such a way that the following conditions are met. There are exactly as many as tents as there are trees. The tents and trees acan be matched up in such a way that each tent is directly adjacent (horizontally or vertically) to its own tree. However, a tent may be adjacent to other trees as well as its own. No two tents are adjacent horizontally, vertically or diagonally. The number of tents in each row, and in each column, matches the numbers given on the sides of the grid. Click in a blank square to place tent and lick occupied square to clear it. Press the space bar while your mouse cursor is over a square to color it green.
