The board extension slides next to the back side of the standard game board, creating a complete board with 70% bigger hexes (the content is the same). All units and resources in Scythe are kept on the board, so the larger hexes provide more space. The standard game board is 624x818mm, and it grows to 818x939mm with this extension.
One Board extension supplied, a copy of the Scythe Main game is required to use this Board Extension.
