Mainland is a strategy game with simple rules that can be played with 2, 3 or 4 players. In order to ensure the survival of your people in a chaotic new world, you must place cards in such a way as to create and expand territories.
Your Mainland is your largest territory. To accumulate the most points possible at the end of the game (and, therefore, dominate the world) you must maximize your Mainland and try to include valuable cards in it.
In this sense, the goal of the game is also to block the territorial expansion of your opponents and to prevent the development of their Mainland.
