Rules

The point value of 3-territories-in-a-row has been reduced from 9 to 6. This was to make the square-of-4-territories more valuable (as it is more difficult). The other option was to increase the square-of-4 value to 12.

See http://forums.superdupergames.org/viewtopic.php?t=8 for a discussion on these interpretations
I decided to disallow double scoring. This means that the same pattern cannot count in two different categories. The corollary to this rule is that rows of the same structure are preferred to rows of the same colour, and longer rows supercede shorter ones.

Assume that all the pieces in the following examples are the same colour.

If you had T C P F M you would receive 5 points for colours, not 5 + 4 + 3 points.
If one has a line T T C C C you would score only 6 points for the 3-structures-in-a-row.
If you had F T T C C C, however, you would score 6 for the 3 structures and 3 for the 3 colours. You would not also receive 6 for 6 colours in a row.
If you scored 2 square-of-4-territories you would receive 16 points, but would not also score 12 points for the two 3-territories-in-a-row implicit in such a pattern.
If two players have the same number of a particular structure, neither gets points for having a majority. Such points are only awarded to a single player.

Choices: This variant allows you to hold up to 6 cards at a time instead of 4.
Total Score: In this variant you can see a running total of eachother's scores, but no itemized breakdown. This forces the system to score the board every turn and can therefore slow things down.
Full Disclosure: This variant implies 'Total Score'. Here the complete scoring matrix is visible and calculated every turn.
