Joy is a one stepper
Quote:
(9=6)r4c6-(6=7)r5c6-(7=8)-r8c6-(8=7)r9c5-(7=9)r3c5
=> r3c6,r6c5<>9

A different one stepper.

Quote:
xy-wing 5-79 with vertex in r4c1 deletes 7 in r9c3 which is really useless. However transporting 7 in r6c3 => r5c2 => r5c6 deletes 7 in r8c6 and completes the puzzle.

All basics. I think I need to get out the eraser and do it again. Sad

This just gave me a great idea. I think that I'll slip in a puzzle with all basics and send everyone into a tailspin. Twisted Evil

You recently slipped me two BBDBers and I was definitely in a tailspin.

What a nightmare!! Three times I made mechanical errors and had to start over. But finally, an X-Wing (6), coloring (7), and an XY-Wing (597) with two pincer transports, not all of which were necessary.
