Tents and Trees Puzzles comes from Frozax Games. It's an old concept from at least 1989. It first appeared in a Dutch puzzle magazine called Breinbrekers.  Leon Balmaekers was the inventor.
  The object is to place tents in the rows and columns such that:
1. Every tree must have a tent next to horizontally/vertically.
2. No two tents can be next to each other horizontally/vertically/diagonally.
3. The numbers at the top and on the side indicate the # of tents.

These puzzles are kind of easy. But they're fun!  I've done about 120 levels. I would have done more, except I have to earn extra coins by either watching ads or waiting 6 hours!  Of course there's an option to buy coins.  I've seen the same 5 second ad for 'slider fries' about 40 times now.
Frozax made the Thermometers game from 2 years ago and Mirrors & Reflections from 5 years ago.
