Very well, now that the site publishes only those sudokus that have a logical solution. Thank you! And does program the device, based on the uniqueness of the solution?

Nothing of the sort! The site contains the same Sudoku that was before, just when you transfer them to a new platform they were regrouped according to other criteria. And decided became much less it was once difficult Sudoku was solved 150-250 times, and now 50-70 times. Something like that...
