Rules:

Normal 4x4 sudoku rules apply.
Remote Sums: A digit X in a cage points to a second digit Y located X cells away vertically or horizontally. The number in the top left corner of the cage indicates the sum of X+Y.
Skyscrapers on Arrows: Digits along the arrows represents the height of a building. A digit in a circle tells you the count of visible buildings along the corresponding arrow (not including the circle), in the direction from the circle to the opposite end of the arrow. A taller building will hide any shorter or same height buildings behind it.
Ta(x)i-Cab Sums: Each clues is the sum of all digits (not including itself) that are X taxicab distance (minimum number of orthogonal steps from cell A to cell B) away from that cell where X is the digit in the cell. For example, if r2c3=3, then r1c1, r3c1, r4c2 and r4c4 sums to 8.
Upper Right Heavy Killer: A cell with a clue contains a digit that is smaller than the digit in the diagonally adjacent upper right cell, and the clue is the sum of those two digits, where a question mark can be replaced by any sum ranging from 3 to 7. Not all clues are given.
Virtual Killer Cages: A shaded cell is given if there exist an orthogonally connected group of cells of non-repeating digits, with at least one cell is horizontally or vertically adjacent to the shaded cell, that sums to the digit in the shaded cell. Shaded cells can also be part of group of cells. All shaded cells are given.
W-Sums: The number on an arrow shows the sum of the first N digit(s) pointed to by the arrow, where N is the digit right behind the arrow.
X-Average: Clues outside the grid indicate the exact average of the first X digits in the corresponding direction, where X is the digit placed in the first cell in that direction.
Y-Sums: Clues outside the grid indicate the sum of the first Y digits in the corresponding direction. Y is the digit placed in the Xth cell in the corresponding direction, where X is the digit placed in the first cell in that direction.
