Pawns travel one hex per move in any of the three forwardmost directions, but they capture hard-forward-left and hard-forward right. (See below.) Note that "forward" for each tridrant is indicated by the red arrows. A dashed white line marks the boundary separating the tridrants. The umber-colored hex at the center of the chess board does not belong to a tridrant.
A pawn that has entered an opponent's tridrant changes its forward direction to face the arrows in that tridrant. In the figure below each of the red pawns is in a different tridrant so each has a different "forward" direction.
The center hex is the only location on the chess board that is not within a tridrant. A pawn that has moved there does not change its forward direction. (See below.)
Each player begins the game with four pawns. A pawn that reaches the far end of an opponent's tridrant is promoted to a piece of higher value. (See promotion.)
