Each player has four pieces. Players start by alternately placing pieces on a 5x5 grid, then alternate moves (moving one piece each turn to an adjacent point on the grid). Object is to get four pieces in a row, or to form a square with your four pieces.In 1998 Guy Steele solved standard Teeko, as well as all variants proposed by the original inventor. The solution was brute force. Standard Teeko (only win with 4 in a row or a 2x2 square) is a draw with perfect play. Advanced Teeko (win with 4 in a row or a square of any size) is a win for the first player.Online Play igGameCenter (real-time) - BoardGameGeek
