3D Tic-Tac-Toe Setup

Use the logo (top left) to Return or Escape

Computer vs. Computer on automatic play is a loop.
To escape the loop click the logo in the top left corner.

For 'Computer plays automatically'
auto-refresh must be enabled.

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.

Winning lines

To get your head around it, consider Two dimensions first...

» In two dimensions, if you score one point for a line of three then X would get two points for going in the top left 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 ⇒
