Another puzzle for Scojo's prompt with row/column indexers and liars this time :-)
My difficulty estimation is 3.5*
I hope you will enjoy and I would be really grateful for all the comments and ratings.
Normal sudoku rules apply.
Row & Column Indexers: Digits placed in cells with double arrows pointing left-right and up-down indicate both the position of the corresponding column number in that row and the position of the corresponding row number in that column. Those are always truth-tellers.
Liars: For each of listed below constraint types (excluding row/column indexers), exactly half of clues is not correct (e.g., exactly 2 of 4 quadruples are missing at least one of the specified digits from its surrounding cells).
Diagonal: Digits along the marked blue diagonals must not repeat.
Arrow: Digits along an arrow sum to the number in the attached circle.
Thermometer: Digits along a gray thermometer increase from bulb to tip.
Quadruples: Digits in a circle must appear within the four surrounding cells.
White kropki dots: Digits in cells joined by a white dot are consecutive.
Black kropki dots: Digits in cells joined by a black dot are in a 1:2 ratio (i.e., one digit will be double the other).
X: Digits in cells joined by an X sum to 10.
V: Digits in cells joined by a V sum to 5.

Very good, I wasn't sure what to put as the difficulty rating as I found it quite hard to fully break in, but it was much easier after that point
