Quarto -- More advanced squares

[Jest Phulin]

Currently, Quarto supports the options of Standard (row, column, or major diagonal [10 options]) or Advanced (additional 2x2 squares [9 more options]) to determine what constitutes a group of four.

I propose that more square categories be allowed:
3x3 corners (A/B, A+2/B, A/B+2, A+2/B+2) -- this allows 4 more win options.
5-corners. These are the squares at 45 degrees on the board, with a space in the center. (A/B, A-1/B+1, A/B+2) -- This also adds 4 combinations
All-corners: Spots 1/1, 1/4, 4/1, and 4/4. - This adds 1 more option.

Or, in text-graphic form

Code: Select all

X _ X _				_ X _ _
_ _ _ _				X _ X _
X _ X _				_ X _ _
_ _ _ _				_ _ _ _

Note: I have not play-tested this, so increasing from 19 to 28 possible winning spaces may give an unfair advantage based on starting player.

Interesting idea. I remember that first time I heard about square rules, I was wondering if the squares you mention fall into the win condition I'll try to play this way a bit on real board, but as for now I think there shouldn't be any problem with first/second player advantage.

Hrm, just realized I can't find this being an official Gigamic variant. But then, I can't find much official from them either, including rules in English.
