:::comment:::
yes, well, there are an above average number of puzzles with this pattern ..... but still not a real game as such with 19C - with all puzzles known... well done JPF
Although, here, it looks like the last entry wins !!!
In the interim I looked at a few more symmetrical 19C patterns, en bulk, and got most of the 4210 puzzles for 14 patterns [~300 puzz per pattern]
the best puzzle/pattern was below 9.9 ... and none had better than ED= x.x/x.x/3.8
so the 10.0 must be approaching the best ED for 19C symmetrical puzzles ...
Another pattern of many

Yes, it's quite perverse that, in a game with an even number of possible highest ratings, ignoring the deal and the dealer, the first player is doomed to lose. Anyway, I'm off now for a few days' respite.

::: comments :::

I understand Mike's frustration.
In fact, the game has its limits when there are only 2 players and/or when the pattern's number of clues is too low.
When the game was designed (12 years ago) I chose 19 clues as the lower bound ; but now this bound is too low because thanks to much more efficient solvers it is possible to list all the puzzles of a 19 clue pattern, making the game much less interesting.

Last point, I got the highest rating thanks to a sudoku explainer's bug:
Here are 2 equivalent puzzles with different ratings:

Code: Select all

1.........3..8.9....6..4.2...........5..9.3....2..7..6.8..3.1....7....4......2...  ED = 10.0/10.0/3.8
1.........2..3.4....5..6.7...........4..9.2....8..7..6.9..2.1....6....8......5...  ED = 9.9/9.9/3.8

( assuming only 2 active players
and both players reach same ratings )

well it just happened that the first response was the losing move.
could've been the winning move!
