In Rampart, the player is in control of a set of castles, which they must defend, by alternately shooting at attacking ships (or other players), and repairing any damage done to them within a time limit. Surrounding this castle is a wall, made up of small blocks, completely surrounding a region of the board. This area is considered the player's territory, and it may contain one or more castles, and any number of cannons. The maintenance of this territory is the primary focus of the game. Once the player defeats the opponent, the player can execute the commander, by walking the plank or beheading.
