This includes the ID of the puzzle, date and time of the solving, and if you selected the puzzle as a favorite.
Registered users can see a list of the last solved puzzles and their favorites.
We are also calculating a rating for you, to ensure that you get puzzles with a difficulty corresponding to your puzzle solving level.
