Speed Dial
- Kropki dots
- XV and number dots
The brief
Normal Sudoku rules apply. There are 4 orthogonally continuous clones of the numbers 1-9 in the grid (numbers are in the same position in all clones). A clone does not touch any other clone adjacent or diagonally. Numbers with an X between them sum to 10. Numbers with a V between them sum to 5. Numbers with a white dot between them are consecutive. X, V and white dots can be outside of, or touching a clone, but never between numbers inside a clone. Not all X, V and dots are necessarily given.
