Rules

Setup: Two players (one blue and one red) are each given 2 pawns, 9 vertical walls, 9 horizontal walls, and one bomb. Pawns are placed on their starting locations (home bases), which are marked on the 11x14 board (red at D4 and H4 and blue at D11 and H11).

Object: The object of the game is for each player to move both their pawns to the home bases of their opponent. The first player to do so wins.

Moving: On each turn, a player moves one pawn to a vacant square and places one wall. Pawns may be moved one or two spaces horizontally, vertically, or any combination of the two without jumping over any walls. If a space is blocked by an opponent’s pawn and the opponent's pawn is immediately adjacent to the moving pawn, the pawn may jump over the opponent's pawn, thus treating the opponent pawn's space as an empty space. Two pawns may not occupy the same space at the same time.

Walls: Walls may be placed anywhere on the board as long as they are placed adjacent to two squares only and do not cut across other walls. Additionally, pawns and home bases may never be completely enclosed by walls; there must always be an accessible path between every pawn and every home base. Once a wall has been placed, it cannot be moved. When players are out of walls, they keep moving pawns until one wins.

Bombs: Before moving, a player may also detonate their bomb against any single cell of a wall (half of the wall) as long as the wall is directly adjacent to one of their pawns. Pawns may then pass through the destroyed section of the wall.

These rules are based on Blockade, a strategy game developed by Lakeside in 1975. Some modifications have been made.
