• Normal Sudoku rules apply, and all clues are standard.
• Dynamic Fog: The grid is covered in fog. Placing a correct digit will clear the fog from that cell and potentially from other cells somewhere in the grid. No guessing is required to progress.
• Killer Cages: The sum of the digits inside each cage is equal to the small number in the top left corner.
• Even Square: Digits in cells with a filled grey square must be even.
• Odd Circle: Digits in cells with a filled grey circle must be odd.
• Light Orange (Entropic) Lines: Every set of three consecutive numbers must include a "low" (1-3), a "medium" (4-6), and a "high" (7-9) number.
• Quadruple Circles: Digits inside a white circle must appear in at least one of the four cells surrounding that circle.
• Kropki dots: Cells separated by a black dot must have a 1:2 ratio.
• Pink (Renban) Lines: Contain a non-repeating set of consecutive digits in any order.
