Rules:

Normal Sudoku rules apply: Place the digits 1–9 such that each appears exactly once in every row, column, and 3×3 box.

Dynamic Fog: The grid begins covered in fog. Placing correct digits will lift the fog from that cell and may also reveal additional cells or clues elsewhere.

German Whispers: Adjacent digits on green lines must differ by at least 5.

Renban Lines: Digits on purple lines must form a consecutive set, in any order.

Palindromes: Digits on grey lines must read the same forwards and backwards.

Arrows: Digits along an arrow must sum to the digit in its connected circle.

Killer Cages: Digits inside a dashed cage must sum to the value shown in the upper-left corner of the cage.

Kropki Dots: A black dot between two cells indicates the two digits are in a 1:2 ratio. A white dot between two cells indicates the digits are consecutive. Not all possible dots are given.
