I am a 74-year-old retiree grinding his way through another Pittsburgh winter. I have been a kakuro fan for many years and enjoy the challenge of the difficult level Puzzles. Last October I decided to try sudoku.

I quickly got to the point where I had to master the world of wings and fishes. This proved to be very difficult. I could not find an explanation that worked for me. I found myself falling asleep staring at a bunch of small number on the iPad. This wasn’t the kind of challenge I was looking for.

I just completed your graduate level training program and I want to thank you for it. You’re alternative to the wings and fishes solutions make it possible for me to enjoy solving difficult puzzles. Working my way through conflicts and coalesces requires a great deal of concentration and focus. And the rewards are there when you come to the solution of the puzzle,
Or when your solution fails in the last box.

I am not going to get hung up on the nuances of guessing . I will leave that to you professors. I just want to thank you again for the many hours of challenging and rewarding mental exercise that awaits.
