== Game Notation ==

While working on this I realized it might be handy to be able to replay games and a game notation would be needed.

While working on this I realized it might be handy to be able to replay games and a game notation would be needed. There is a defacto standard which is used for downloadable games found on the [http://www.morpionsolitaire.com/English/RecordsGrids5T.htm Morpionsolitare.com records page]]. These games can be replayed on the [http://pentasol.systemutvecklarna.se/ Pentasol player].

<pre># Morpion Solitaire game

The advantage of using this system of output is that the Pentasol player will validate the game and provide an image of the result.

The above is taken from [[http://www.morpionsolitaire.com/Grid5T177RosinA.txt Rosin's 1st 177 move game]]. The first line references the final position of the north-west valley. Each line is a set of coordinates followed by a direction and a distance. I haven't found an explanation of the final integer; however, they appear to be 0,1,2 indicating where the center of the line is relative to the move (center=0, top/left end=+2, etc.). Also the order of coordinates here is '''(column, row)''' the reverse of what I used. --[[User:Dgamey|Dgamey]] 12:18, 9 February 2012 (UTC)

The notation looks like this:

While I was unable to find a detailed description of the format, what I worked out is in the annotated comments above. Comment lines are preceded by hashes. The first line references the final position of the north-west valley of the starting cross. Each line is a set of coordinates of the move followed by a direction and an offset to the center of the line created by the move. The table in the comment above tells you how to figure out where the start of the line is. All coordinates use (column, row) order. --[[User:Dgamey|Dgamey]] 13:41, 13 February 2012 (UTC)
