It’s nice to be able to feed back directly to the setter hamishsoup. I really enjoyed this as I try my hand at the specialist sudokus as well as crosswords. I appreciated the relatively generous clueing for the non jumbled entries. It was good to have an early framework to hang the jumbles on. I found the jumbles much more challenging so overall a good workout.
For whatever reason I did not immediately twig that two identical pairs of possibilities in a row, column or square would mean those two letters were accounted for. So in standard sudoku if you have either S or F in one cell and S or F in another one must be F and the other S. Here they could also be S and S or F and F.
That led to needing a restart when I was pretty sure I had nearly finished.
The final solve was 40a which I only managed to reverse engineer after completing the grid. A nice confirmation that I have (probably) got it right.
So it’s a thumbs up from me. Many thanks.
