Zero cases where there are multiple solutions. Too many cases where the solver doesn't read the instructions. :)
If there is no 'X' or 'V' between squares then the squares do not sum to either 10 or 5. You need this 'negative' rule to get a unique solution for the XV, Kropki and Consecutive puzzles on the site.
To view instructions, which are highlighted via the large red-and-yellow text that appears at the top of every puzzle when it first opens, click 'Sudoku XV rules' at the bottom-right of the XV player, or similarly for any other puzzle type. Or click 'Instructions' at the top of this or any other page.

Key
A yellow/light blue highlight in the time distribution charts highlights your time, where relevant.
Rating scores out of 10.0 show the average difficulty rating chosen by users, where 1.0 is "Easy" and 10.0 is "Hard".
If a puzzle is opened more than once, including by loading from a saved position, then this is potentially a significant aid so it is listed as being completed with 'multiple sessions' for the purpose of the best time/average rating displays above.
Minor aid is defined as no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or using highlighting aids (show repeated digits, show broken inequalities and show valid/invalid placements [slitherlink] only). Major aid is any and all other use of the solving aids except for 'show wrong'.
