You wake up on a sandy beach. The sun is burning your back, the salt of the sea makes your skin itch, your tongue barely moves in your mouth... You remember a huge wave that swept you overboard, and soon you lost sight of the ship. You are lucky to be alive. But where are you? Is this place inhabited and do ships sail by? Will you ever return to your homeland? And can you even survive here?

Washed Ashore is a story-driven solo adventure in which the player takes on the role of the main character who is shipwrecked and stranded on a deserted island. The player reads parts of the story on cards and makes decisions related to those situations, the consequences of which are revealed to the player either immediately or over time.

As the player progresses through the game and follows the story map after map, he finds or creates resources that he can use further to achieve the goals of the game.

The game consists of several parts/chapters, in which the main character tries to get off the island, discovers a tribe of natives and lives with them, and tries to sail to his homeland on a ship that has sailed to the islands.
