Pegity

Background

Peg'ity is played on a pegboard, usually 16 holes by 16 holes, with four sets of colored pegs. To begin play, the first player places one of their colored pegs in any hole. Play passes to each player in turn, one peg being placed per turn.

Each player attempts to place five of their pegs in a straight line in adjacent holes either horizontally, vertically, or diagonally. At the same time, players try to prevent others from achieving the same threshold by placing one of their own pegs at one end of an opponent's line of pegs while it still has only three pegs or fewer. Then if the player with three in a row places a fourth, any player can completely block five in a row by placing their peg at the other end of the four.
