Rules:

Normal 4x4 sudoku rules apply.

Clock Faces: Four numbers around a circle must strictly increase starting from one of the four cells and going clockwise (white circle) or going anticlockwise (black circle).

Skyscrapers: Each digit represents the height of a building. Clues outside the grid indicate the number of buildings visible from the corresponding direction. A taller building will hide any shorter buildings behind it.

Ascending Starters: Clues outside the grid indicate the sum of the first set of all ascending digits, starting from the first cell in the corresponding direction. Sets may consist of only one digit.

Up to N: A clue outside Row N (counting top to bottom) indicates the sum of all digits up to the cell that contains the digit N. The digit N itself is not included in the sum.

Sandwich Variant: Shade exactly two cells in each row, column and box. A clue outside the grid indicates the sum of the digits which appear between the two shaded cells in the corresponding row or column. Additionally, the shaded cells contains each digit from 1-4 exactly twice.
