Page 7 of 18 Focus was invented by Sid Sackson. Focus is played
on a square board with some of the corners removed. Here is the
board with the pieces in the initial position. Players move, and
must move, in turn. White moves first. In Focus stacks of men
emerge in any combination of colors. A stack is owned by the
player who's color is on top. - On his turn a player moves a man
or a stack of men horizontally or vertically, based on the
number of pieces to be moved (e.g. one piece moves 1 square and
a three-piece stack moves 3 squares). Stacks may be split in
this process: a player may choose for instance to move only the
top man (1 square) or the top two men (2 squares) of a higher
stack. - When a stack grows over five pieces tall, the remaining
men are removed from the bottom of the stack. Men of a player's
own color become 'reserves' to be re-entered into the game at a
later time, while pieces of the opponent's color are captured. -
Instead of moving a piece, a player may choose to enter one of
his reserves
