Treblecross

Treblecross is a degenerate tic-tac toe variant.[1] The game is an octal game,[2][3] played on a one-dimensional board and both players play using the same piece (an X or a black chip[4]).[5][1][3] Each player on their turn plays a piece in an unoccupied space. The game is won if a player on their turn creates a line of three pieces (Xs or black chips) in a row.[1][4][6]
