The annotations for the puzzle game use a simple context dependent format.
This format is explained below using an example from the actual annotations.

Example:
------------------
The game grid is shown below for game 1, with the rows and columns numbered.

      0 1 2 3
    -----------
  0 | # # . . |
  1 | . . . # |
  2 | . . . # |
    -----------

The annotations for this game are as follow:

  1
  r:0:0:1
  c:3:1:2

The first line of the annotations simply indicates that this is for game 1.
Subsequent lines list the correct sequence of game actions:
The second line shows the correct first action in the game - i.e., "remove 
the row which starts at coordinate [0,0], and ends at coordinage [0,1]. The
The third line of the annotation is the second action of the game - i.e., 
"remove column which starts at [3,1] and ends at [3,2]. 

The format of the annotations is different for row actions (starting with 'r')
and column actions (starting with 'c'):

  r:[row]:[starting column]:[ending column]
  c:[column]:[starting row]:[ending row]
