starts a new game for two players.
The -size parameter specifies the board size (default 5).
Octex is a 3D path-making game played with octagonal pieces.
Tiles: Two players, O and X, share a common pool of octagonal tiles divided into four coloured regions:
--- ---
/o|x\ /x|o\
|--+--| |--+--|
\x|o/ \o|x/
--- ---
The front and back faces of each tile have a square coloured bump that connects two opposite corners of that colour, giving four unique rotations:
--- --- --- ---
/o|x\ /x|o\ /o|x\ /x|o\
|--o--| |--o--| |--x--| |--x--|
\x|o/ \o|x/ \x|o/ \o|x/
--- --- --- ---
Start: The board consists of an 5x5 grid of square holes which is initially empty.
Play: Players take turns placing a piece to nestle in either:
1) An empty board hole, or
2) The square hole formed where four tiles meet on the same level.
The following example shows a stacking move in which a tile is placed to nestle in the square hole formed by four mutually adjoining tiles. Note that that there is initially an X path running from top left to bottom right (left) but that the move breaks this path (right).
--- --- --- ---
/x o\ /o x\ /x o\ /o x\
| x | o | | x --- o |
\o x/ \x o/ \o /x o\ o/
--- --- ----> -| o |-
/x o\ /x o\ /x \o x/ o\
| o | x | | o --- x |
\o x/ \o x/ \o x/ \o x/
--- --- --- ---
Aim: A player wins by forming an orthogonal or diagonal line of three bumps of their colour, such that a path of the same colour (not including any bumps) can be traced between the bumps at each end of the line. If a move achieves this for both players then the mover loses.
The following example shows a game won by X, who has formed a vertical line of three X bumps with a bumpless path between them:

The name Octex refers to the tiles having eight (oct) sides and six (hex) distinct coloured parts, in addition to the 'X' shaped colouring patterns on the tiles.
