If you like challenging visual puzzles, you will like The Bird Puzzle. The puzzles are set up on either a 3x3 or 4x4 grid. Some of the cells are empty. One cell contains a bird and another cell contains a cage. The goal is to get the bird into the cage. A marker is used to slide objects in order to move the bird.
Some of the puzzles might seem simple at first but actually they are deceptively difficult; so get ready to put your logical reasoning skills to work.
