Normal Sudoku rules apply. Additionally:
1. Standard killer cages: digits in cages must sum to the number in the top left corner of the cage. Digits cannot repeat in a cage.
2. Standard littler killer: clues outside the grid give the sum of cells along the indicated diagonal. Digits can repeat along these diagonals.
3. Standard XV: cells separated by an X must sum to 10; cells separated by a V must sum to 5.
4. Logic gate dots: cages connected by a white dot must contain all the same digits.
