Tents Tents is a puzzle you can find in several places on the Internet.
Locate the tents in the grid. Each tree is connected to exactly one tent, found
in a horizontally or vertically adjacent square. Tents do not touch each other,
not even diagonally. The numbers outside the grid reveal the total number of
tents in the corresponding row or column. Clicking in a blank square will place
a tent in it. Pressing keyboard 'space' in a blank square will colour it green
indicating, that you are sure it isn't a tent. Clicking button in an occupied
square will clear it.
