The Isle of Cats family mode provides a beginner friendly, gateway game which can be played by anyone new to the board game hobby, and children. It removes a lot of the complexity included within the standard game and simplifies the setup, learning curve, and decisions players have to make.
It also makes the perfect introductory game, as once you are comfortable with the family mode and are ready for something more challenging, you will already know some of the rules for the standard game.
