Solution
a=abs(x) b=abs(y) return z==0 and(a==b and a<2 and 7 or abs(x-4)+abs(b-4)==1 and 11 or a==2 or b==2)How it works
It’s a tic-tac-toe board! Everything lives on the z==0 plane, which is our first gate.
The X marks sit where abs(x)==abs(y) (the diagonals) and both are small (<2), so just the center cell’s X pattern. Those get painted red.
The O mark is a diamond shape centered at (4, ±4). We check it with the classic Manhattan distance trick: abs(x-4)+abs(abs(y)-4)==1 catches the four points exactly 1 step away from the center. Since abs(y) is already stored in b, we reuse it as abs(b-4). Those get green.
The grid lines are wherever abs(x)==2 or abs(y)==2. Since WHITE is color 1, we let the bare boolean true do the work at the end of the or chain. No and 1 needed!
