Normal sudoku rules apply.

Dynamic Fog: Some parts of the grid are covered in fog. Placing a correct digit clears the fog underneath itself and possibly other cells.

Yin Yang: Shade some cells such that all shaded cells are orthogonaly conected and all unshaded cells are orthogonaly conected. No 2x2 area of any region can exist in the puzzle. Adjacent digits in the shaded region have different modularity when divided by 3. Digits in the unshaded region have at least one neighbor that breaks the rule of the shaded region.

Black lines: They act as both german whispers (adjacent digits differ by at least 5) and region sum lines (box borders divide the lines into segments of equal sums, different lines may have different sums).

Renbans: Purple lines form a non-repeating consecutive sequence of digits in any order.

Killer cages: Digits in cages sum to the number in the top left, if given. The cage with no total given is part of the shaded region.

Kropki dots: Digits separated by a white dot are consecutive. Not all dots are given.

Duality dominos: Cells separated by a D are in the same region and may or may not contain digits that follow the rule of the opposite region they are in.
