Hi Tarek,
Perhaps you can send me your email address via the forum system and I can send you the list. The text file is about 34 MB but an Excel file is smaller at 13 MB, so you can nominate your preferred format.
BTW The "official" count is currently 422,969 but is rising slowly (about 700/week) as I have been forced into a [+-3] search for new puzzles. I'll never actually finish this (or even make a serious dent in it), but I'm hoping that the supply of new puzzles will just dry up and I can use a statistical argument to say that I have "probably" found "most" puzzles.

With that variants enabled Sukaku explainer I've attempted to rate large collections of known variants and the 12 clue sudoku X is a good example of that. Thanks to Leren for supplying the 400,000+ puzzles that are still being updated.
I managed to iron out a few issues with the help of the puzzle variety but there were very tough puzzles in the collection that unfortunately will make me curtail the full task and possible re-rate with the nested chains disabled.
Here are some monster puzzles rated. The 1st part shows the options used with sukaku explainer. The puzzle will be followed by the ER/EP/ED the the short description of these techniques with that ER/EP/ED rating
The solver has been attempting to solve for hours the following puzzle but hasn't given up yet which is at odds with the longest time required by by one of the 12.5 puzzles. It will be either a very difficult monster puzzle or there is some bug in the code

Tarek you probably have bugs, because those are all lower than SE 10.0. (or 10.4)
Here are my timings:

Thanks creint,
The bug was found in the chain search algorithm which is fixed ….
This now means I can re-rate the entire collection hopefully.
I'll report back here

Thanks.
I ran the first 10,000 through SukakuExplainer, and here's a selection of the results (in SE order):
Curiously, there was no 1.2/1.2/1.2.

ton's 12 clue puzzle list contains 543,985 ED puzzles, about 110,000 more than my paltry list of about 434,000 puzzles. But it's not all there is. My list contains the following 964 puzzles not in ton's list.
I'll add these to ton's list, to make a combined total of 544,949 and continue on.

To obtain a more representitve selection, I processed every fiftieth puzzle instead of the first 10,000 (up to 500,000). That took longer, and any higher ratings for a given ER are shown here:

These are all proper SudokuX with a single solution, I presume.
Hidden Singles in boxes have SE 1.2 . In rows or columns SE 1.5.
Probable you cannot solve the puzzle without the use of the diagonals constraint.
Presumably the diagonals have SE 1.5 also.
So you won't find 1.2/1.2/1.2.
PS what are "Generalized Intersections/Naked Pairs/... etc"

Not quite sure, but in my memory tarek tries to include all sorts of things in one big box. It is natural for him to be inclusive; as he comes from the east and also the west (of the English Midlands of course).

All candidates that are peers to the locked candidates are eliminated … In Sudoku variants, the eliminations may go beyond the interacting 2 houses (sectors)

My solver solved all except these 62:
Adding one more dynamic part would solve them all.
