This puzzle had a lot of bivalue cells with digit <2>, but I never found a "killer" move. Instead it took four steps; | Quote: | w-wing24 with transport,
w-wing28,
kite5,
w-wing23

Congratulations Ted. The set Z_nn puzzles are especially difficult.
The set T_nn puzzles are more along the line of Bend But Don't Break.
The set XY_nn puzzles are like the T_nn puzzles with an XY-Chain probably needed. |
