Critter 3 is a unique, fun, free puzzle game based around a cube world. Think of it as a cross between Rubik`s Cube and Sudoku.
Open the game and choose a difficulty. A mouse is also helpful. Once in the level, use the right mouse and drag to look around.
Each center cube represents an animal population. You must save them from going extinct by placing resources (mountains or forests) around them. If a resource is correct, you will notice an animal appear.
If it is incorrect, they will disappear. Be careful though, you are timed. Animals will go extinct without resources.
You will see this happening by the color of their cube - dark means you`re in trouble! A good strategy is to start on one side and move side at a time.
The last will be the hardest, but swapping cubes will help you save the animals from extinction! If you encounter an automatic win screen, just restart the app and you should be golden.
