The board will show lines that have just added to the score.

Rules

Each of the two players uses 'X' or 'O' as a token, and they take it in turns to occupy available squares.
Any line of three occupied squares (in any direction or dimension) scores a point.
The winner is the player with the most points when all available squares have gone.
The most central square gives too much advantage and is not available to either player.

Scoring Lines

» In two dimensions, when you score a point for each line of three, X would make two points for going in the top left hand corner in this situation ⇒

» In three dimensions with one board conceptually above the other, X would make three points for going in the top left corner of the lower grid in this situation ⇒
