There are different theories of the appearance of dinosaurs on Earth, and then their unexpected disappearance. One of them is that they are aliens from outer space. In the Puzzle Bemeunsterd we support the most insane ideas associated with aliens, and you begin to pass the levels. For this, look for two or more identical tiles on the playing field and click to remove. The goal is to remove all creatures from dinosaurs of different species to strange creatures from other planets. If the elements are left and can not be removed, use the stones. But remember that their number is limited.
