Sum Get Half as Many
by Alexander Hamilton Open on SudokuPad
GAS
- Killer cages
- Kropki dots
- Kropki ratio
The brief
- Normal Sudoku rules apply. - Digits in cages must sum to the number in the top left corner of the cage. Digits may not repeat within cages. - Cells separated by a black dot have a 1:2 ratio. Not all dots are necessarily given.
