The game consists of a board of squares of various terrains in which players move around units and try to get a particular unit to the goal, a floating gray exclamation point. Each different unit requires an amount of bricks to create, but in order to create a unit, one must obtain a "plan." Different units do different actions and move at different speeds. If the player has achieved the goal of a level, it appears as a red flag in the main menu. If, in addition, the bonus goal has been reached, the flag has a star on it. Unsolved levels appear as question marks.
