Hi Mathimagics,

Do you still have the list of the 12 clue SudokuP puzzles so that I can rate them with Sukaku explainer.?

Any other list of SudokuW (and / or PW WX PWX) can also be rated

I'm not sure if blue still has a list as well or not!

Thanks

started with Leren's PX list … I'm not sure if the list is a collection of random 10 clue puzzles or not but from the 1st 1000 puzzles it appears on average to have difficult puzzles and non singles puzzle. already there is an ER=10.6
Code: Select all
.....................................1.....23.4..5.......1.....4.6...7.....8..... 10.6/1.5/1.5 DCFC+FC/HS/HS


Update:
We have breached the ER=11.0 barrier with the SudokuPX. It will be good to know if you think that these rated by v1.14.5 are as difficult as they would appear
Code: Select all
...................................1...........2....345.....6.....47....8.....9.. 11.5/4.3/2.9 DCFC+DFC/g2SK01/gI
...................................1......2....3.........4...5.6......4.27..8.... 11.3/1.2/1.2 DCFC+MFC/HS/HS
...................................1......2....34........5...4.6.....1...7...8... 11.0/2.9/2.9 DCFC+MFC/gI/gI
...................................1......2....34........53..6.7.........8..9.... 11.3/2.9/2.9 DCFC+MFC/gI/gI

Might be worth switching to the Sudoku PX thread to discuss the PX results, to avoid going off topic. Leren

At 68493, the grid count is just a tad shy of the range predicted by blue (68687 - 72631), so .....

but
