Overlord is a "2 player game of pure 3D strategy". The game is played on a 7x9 board with a crenellated wall located on the middle row between the two players. Both players have 14 pieces located in the back 2 rows on each side of the wall and attempt to capture the opponents pieces by landing on top of them. Pieces move and stack in various ways, and the game is won when one player is reduced to a single stack.
