The game is a puzzle game where you have to place cheese, mice, cats and dogs on the board to match the required target.
The idea is simple but as the level number increases, so does the difficulty. You start on a 3x3 board and progress to a 7x7 board, always against the clock.
A mouse will become happy if it is closer to more cheese than cats, a cat is happy if it is closer to more mice than cats or dogs and a dog is happy if it is closer to more cats than dogs. The game starts off quite easy with only cheese, mice and cats available but when you complete the 6x6 grid levels then the dog comes into play.
There are 200 levels of increasing difficulty where either the board size increases or the time available decreases.
There is also a tutorial to help you through the first level.
