Reclaim is a flip-and-write game where players will be drawing polyominos on their board and drawing triangles within certain terrains of already placed shapes to pay the cost of the new shapes. Once a shape has been entirely filled with such triangles, the triangles within that polyomino are shaded in. After 10 rounds, an initial scoring happens, where players earn points based on the number of castles connected by paths of hollow triangles. After a few more rounds, where the costs of placing a piece have doubled, players again score for connecting castles with hollow triangles but also the largest rectangle of shaded triangles (and castles). The player with the most points wins.
