Normal Sudoku: Place the digits 1 to 9 in every row, column, and white or gray 3x3 box.
Labyrinth: Horizontally and vertically adjacent digits must have a difference of 3 or less except when separated by a wall (thick black line)—digits separated by a wall may have any difference.
XV: Digits separated by an X sum to 10. Digits separated by a V sum to 5. Not all Xs and Vs are necessarily given.
Solve online: (Turn off conflict checker)

Very enjoyable and original puzzle! I haven't seen this labyrinth rule before.

That was fun. At first, moments after filling in the X clues, I thought ... "This is going to be one of those slogs where every digit is a chore." But it turned out to be just the right balance - not too easy, not too hard.
