Rules:

• Sudoku: Place the digits 1-9 once each in every row, column and box.
• Disjoint groups: Cells in the same position relative to their 3x3 box may not contain the same digit.
• Region sum lines: Box borders divide each blue line into segments with the same sum. Different lines may have different sums.
• Renban: Digits along a pink renban line form a set of consecutive non-repeating digits in any order.
• Kropki: Digits in cells separated by a black dot are in 1:2 ratio.
• Killer: Digits in a cage must sum to the total in the top-left corner of the cage.
