HoDoKu Two String Kite
There are only two positions for {0} in both {1} and
{2} (the two strings), and they both hit {3}
(the kite), therefore {4} cannot be {0}.
The logic is: There are only two possible positions for {0} in {1}:
- If cell {5} is {0} then {7} cannot be {0} (same box),
therefore {8} must be {0} (only remaining position in col),
and therefore {4} cannot be {0} (same row).
- Alternately, if {6} is {0} then {4} cannot be {0} (same col).
Hence there's only two places for {0} in {1}, and neither allows {4} to be {0}.
Therefore {4} cannot be {0}.
