+7r9c5; Pointing{1B9, 6B8} -> -{1r4c8, 6r3c6}
Note : 2r1c2 -> 2r3c9, Jellyfish{8R1578} -> -{8r4c8}
2r1c2 + 3r3c8 -> 0 solution
2r1c2 + 4r3c8 -> 0 solution
2r1c2 + 8r3c8 -> 0 solution via WWing(43)r4c3.r7c5,3C3 - 4r3c5=4r3c2 -> +4r3c2
2r1c7 + 1r5c1 -> 1 solution via {9B8} -> +9r2c3
2r1c7 + 1r5c3 -> 0 solution |
