Blokus Duo

Rules that are true for all Blokus verisons:

Each new piece played must be placed so that it touches at least one piece of the same color, with only corner-to-corner contact allowed—edges cannot touch. However, edge-to-edge contact is allowed when two pieces of different color are involved.

When a player cannot place a piece, he or she passes, and play continues as normal. The game ends when no one can place a piece.

Final points counted by the placed cells by color.

Blokus Duo is for two players only, and uses a 14×14 board; the piece colors are blue and yellow.

The two starting squares are placed in the (5,5) and (10,10) cells. This makes a crucial difference in the flavour of the game, because players' pieces may (and usually do) touch after the first move. Even more than with the original game, Blokus Duo is an offence-centred game; it is also a much purer strategy game than the four-player game, since one is not in danger of getting ganged up on by three other players (as sometimes happens with the four-player version).

This is a side-project of mine, far from ready, so expect updates since it is missing some vital functions.
