Win by moving a piece to the opposite corner. Pieces move one space in any direction except that a piece in its home zone (shaded) cannot move diagonally.
 
Oddly enough, Zonesh was conceived as a 2D variant of the 5D game Skava. The rules are the same except for the ability of pieces in Zonesh to move diagonally once outside of their home zones. This rule compensates for the reduced freedom of a 2D board and makes draws virtually impossible.
 
Zonesh, along with Skava, Breakthrough, and Sidewinder, belongs to a limited class of attainment games characterized by undifferentiated pieces. Declaring a win-zone on a board permits an extraordinary simplification of rules without loss of depth.
 
Zonesh comes in 5x5 and 6x6 versions.
