In the Oceans: Solo expansion, you face an automated opponent named Nautilus. Explore the depths alone and discover if your species can survive and thrive against the challenges of unknown waters. The expansion features no changes to the core rules of Oceans and an automated opponent that is simple to learn. Oceans: Solo can be used both to learn how to play the base game of Oceans as well as to play by yourself. After achieving the minimum score for victory, players have the option of multiple levels that increase the difficulty. Between various ways to modify, players are able to control the complexity and challenge that best suits them. -description from designer
