HighGround is a game intended to simulate the advantage of occupying strategic locations. The outer, or lower, layers of the board must be full before pegs can be placed on the inner, or higher, layers.
 
Pieces can be captured in either of two ways: a piece surrounded by two enemy pieces can be captured; if a higher layer is completely controlled by one player, they may capture pieces on the layer below it.
 
In the higher two variants, control of the third layer of a black board allows a player to capture the third layer of an adjacent white board.
 
Try to set up gaps between your pieces where your opponent will be forced to play at some stage. It is preferable not to play the final piece onto the second layer, since it is very good to occupy the top layer of the board.
