• Normal Sudoku rules apply.
• Kropki Dots: A black dot between cells indicates cell values with a 2:1 ratio. A white dot between cells indicates cells with consecutive values. Not all dots are given.
• Purple Renban Lines: Digits on purple lines are a set of consecutive digits, without repeats, in any order.
• Green German Whispers Line: Consecutive digits on a green line must differ by a minimum of 5.
• Region Sum Lines: Box borders divide each blue line into segments with the same sum.
• Skyscrapers: Clues outside the grid count the number of cells seen inside the grid of its row or column. Each cell is a skyscraper of a height corresponding to its value and taller skyscrapers block sight of shorter ones.
• Dynamic Fog of War: Parts of the grid are covered in fog. Placing correct digits may clear some fog somewhere in the grid.
