Apex is a two-player game upon the cells of an 8x8 field.
 
Each player uses two opposite board edges to introduce Stones. White has the first and eighth rank, Black has the first and eighth file. Each player has 11 Stones.
 
At each turn, the player must do one of the following:
Drop a Stone.
Move a Stone.
Capture a Stone.
 
A Stone is dropped into an empty cell on one of the board edges controlled by the player. After dropping, the Stone may slide, orthogonally or diagonally, until it meets another Stone or a board edge. The Stone may stop at any cell.
 
A Stone is moved by sliding orthogonally or diagonally until it encounters another Stone or a board edge.
 
A Stone captures by sliding into a non-adjacent cell occupied by the opponent. The captured Stone is returned to its owner for further play.
 
The game is won by the player who is able to form a chain of Stones connecting their two board edges. Stones are considered adjacent both orthogonally and diagonally.
 
Jumping is not allowed. The capture of an adjacent Stone is not allowed.
 
 
The game was entered in the 2001 8x8 Game Design Contest, and considered among the best.
