In Explorers, each player places 4 different landscape tiles into the frame of their individual game board, along with 3 scoring tiles. Landscape tiles show four different terrain types: grasslands, bodies of water, desert, and mountains. On your turn, you reveal a scroll, which indicates the landscapes you are allowed to cross off. The active player crosses off 3 spaces for the terrain type they choose, while other players can cross of 2 of the same type or 3 of the other type shown on the scroll.
