Rules:

• Sudoku: Place the digits 1-9 once each in every row, column and box.
• Fog-of-War: The grid is covered in fog. Placing correct digits will clear the fog from surrounding cells.
• Sandwich Sums: Clues outside the grid show the sum of the digits between 1 and 9 in that row or column.
• X: Digits in cells separated by X sum to 10.
• Arrows: Digits on an arrow sum to the digit in the arrow's circle.
• Killer Cages: Digits in a cage may not repeat and must sum to the number in the corner of one of its cells.
