It's here: User statistics page
The link will only work if you are logged in.
Unfortunately I seem to have deleted puzzle play information some time in 2013, so your statistics prior to 2013 may be mostly or completely empty, if you've been using the site longer than that. I do have them on an old PC in database backups, so I will try to recover them before I add this link into the main part of the site.
Currently you can only view your own information. Once I have completed the feature, I will let you opt in to making your profile public.
The next step will be to allow users to be ranked against one another in various criteria, which again will be opt in.
Here are some static ones for now:* The total number of puzzle plays on Puzzlemix is almost 6.7 million: 6,691,303 plays to be precise, not including plays of the demo players on the front page. However I have deleted some old stats, so I think the actual total is around 7.1 million.
* The most puzzle plays of any user (times a puzzle is opened) is an impressive 87,517 plays
* There have been 28,618 separate puzzles published to date
* The first user registered on 20th November 2006
* There are over 18,000 registered users, of whom 14,350 have actually played the puzzles (the rest just registered - some will have been spamming account attempts, no doubt)
* There are currently 210 daily puzzle subscribers (although I don't keep track of the total number of distinct users who have ever subscribed)
* There are 86 'books' of puzzles available to add, containing 7,505 puzzles in total
* There are 777 users who have added at least one book of puzzles to their account (although some had them added automatically, e.g. when I added one for all subscribers last year). In total 2,973 books have been added.
* 11,711 comments have been made on the puzzles
* 551 comments have been posted not on puzzles (i.e. in this forum only) across 93 separate topics
* I have posted a total of 1,694 comments out of both of these last two totals :)
* The largest puzzle yet published was a 44 x 44 Hanjie, only available now for users who have access to the legacy sets page (which is anyone who purchased a set before the current book system was introduced). The same set also included a 48 x 32 puzzle.
I don't know about other countries or companies. But my internet provider at home changes my IP address every 24 hours. Sometimes I check your site with my laptop (not on my PC that I usually use to play). On my laptop I'm never logged in.The same thing might be the case if people play anonymously on their mobile device using wireless on different airports, open hot spots...
So do you have a number how long people in average wait before they become a daily subscriber?
I have never tracked conversions, no, so I can't answer that. It would be interesting to know though. The problem is that when a subscription expires currently the site just deletes that information - it doesn't keep any record of previous subscriptions - so I have no easy way of querying that, unless I reconstruct that information somehow. It might be possible from Paypal records, but I don't know if they extend back very far.
Probably the most sensible change I could make would be to add ads for non-subscribers, but I have no plans to do that.
It seems I also must have deleted lots of older puzzles at some point, since that's where the previous count came from (by summing the play count for each puzzle still in the database). So even the 1.3 million statistic above must be an underestimate for the same reason, meaning that should probably be 1.75 million for a likely total of 7.1 million plays.
Of puzzles with more than 5 ratings, the hardest-rated is 'Wraparound Sudoku 89' from '100 WRAPAROUND SUDOKU VOLUME 1', with a rating of 9.3/10 and an average solve time of 1 hour 7 minutes!
Taking puzzles with more than 5 plays, the slowest average solve is 'Jigsaw Sudoku' 98' from '100 JIGSAW SUDOKU 12X12 VOLUME 1', with an average solve time of 1 hour 22 minutes.
And... that previous puzzle, the Jigsaw Sudoku 12x12 one, has never been solved without significant aids. So that's possibly the hardest puzzle on the site.
Edit: My question really is, how significant is the difference? I know from experience that Hanjie, for example, takes longer on my tablet than laptop, but I wouldn't expect there to be as much difference in time for, say, a 9x9 Sudoku. Also, I could finish puzzles more quickly on my laptop if I had a numeric keypad (not that you'd have any way of knowing whether one was used!).
Unfortunately the site doesn't preserve that information. The player tries to guess what you're using, but it doesn't store what it concludes. Perhaps it should - I do agree that average solving times on many puzzles will differ. It could also simply be stored anonymously as a set of overall averages.
But in any case, it isn't at the moment so I'm afraid I can't answer your question.
You can however view other players' statistics and comments in the tables above.
