Players start by placing one piece along the edge on their side of the board.
They then start building their puzzles as fast as possible with the restriction that every piece they place on the puzzle must connect to one of their pieces which is already on the board. As they expand their puzzles they will complete certain key facilities. When they do, they can claim the facility by placing one of their flags on the board. Two facilities, the paratroop and tank bases, have special functions. When these facilities are completed the player may place their tanks and paratroopers on the board.
