Listener No. 4414: Quads II by Shark IP: 184.108.40.206 Posted on September 24, 2016 at 12:36:44 PM by John Nicholson
I thought that this was one of the best puzzles so far this year, but that is no surprise as it comes from one the best setters. Shark’s grids are always something special. I suspect that the endgame was quite a bit easier for those of us who have grid building software than for those who don't.
