Treblecross


Treblecross is a degenerate tic-tac toe variant. The game is an octal game, played on a one-dimensional board and both players play using the same piece. 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 in a row.

Gameplay

The game begins with all the 1×n spaces empty. Each player plays an X on the one-dimensional board in an empty cell. The game is won when a player creates a row of 3 Xs.
