I see an idea in the look and say cage with sums 'n' renbans
- Kropki dots
- Region sum lines
- Renban lines
- Little killers
The brief
Normal sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box. Digits in a cage may repeat. Read the clue out loud, which describes the nature of the cage. E.g. 1522 says there is “one five and two two(s)” in the cage. Digits on a purple renban must form a set of non-repeating consecutive digits that may appear in any order. Box borders separate the blue line into equal sums. Clues outside the grid give the sum of the digits along the indicated diagonal, digits may repeat. Cells separated by a black dot has one digit double the other (1:2 ratio).
