Listener 4360: What a Turn-up! by IOA IP: 188.8.131.52 Posted on September 11, 2015 at 03:56:40 PM by Robert Teuton
I gave up on this one quite quickly, then reread the preamble this time noting the stipulation about the filled grid retaining symmetry - this made the puzzle solvable!
Once again a setter of a numerical has come up with a different, interesting idea, and another angle with the logic required to work through the solution. I suppose there was a quibble the 1s not retaining symmetry, but nevertheless I really enjoyed the solve. The trickiest thing for me was remembering to flip the 6s and 9s as things progressed.
A hearty chuckle was raised when the entry for 1 Across materialised - thanks IOA. Replies:
