Score four

Score four is a "three dimensional" abstract strategy game, similar to Connect Four (Milton Bradley, 1974).

The object of score four is to position four beads of the same color in a straight line on any level or any angle.

[1] As in Tic Tac Toe, Score Four strategy centers around forcing a win by making multiple threats simultaneously, while preventing the opponent from doing so.

The game has also been introduced as "tic stac toe", but with the introduction of a blocker piece for each side.

The blocker piece is of neutral color and cannot complete a winning line.
