Thanks to both, this is a bad copy of the pattern game.
The wrong puzzles have been discarded,

On the top of my todo list, I have to submit again the entire list of potential hardest played in the games, but as noticed coloin, these good puzzles are already there, so the update should be neutral for these 3.

I prepared a new update of the data base

as for all new files , that update is in my "google drive space" with the name ph_807.zip

the link to that storage place is here

Most of the additions are coming from David Filmer who worked hard in the vicinity of the top known puzzles and from the pattern game (published or not).


The file contains now 1 959 402 puzzles (1 943 739 in the former release)

the count per clue in the data base is the following

the count per clue in the data base is the following

clues Count

20 79 +2
21 10942 +148
22 88039 +814
23 392054
24 702831
25 441576
26 323669

The changes of the count in the low ratings are partly linked to david Filmer search and partly to additions out of the games

The count per er is the following

er Count
11.9 10 +1
11.8 54 +1
11.7 114
11.6 190 +1
11.5 582 +3
11.4 1426 +2
11.3 8600 +6


The main fact is the entry of 2 new puzzles rating >=11.8 thanks to David's intensive search.

I intend to update later this year files showing exotic patterns

EDIT : problem with google drive solved, the file is ready for downloads
