How Many Primes Fit In A Box?
- Killer cages
- Kropki dots
- Arrows
The brief
Come to think of it, how many odd numbers can be in a prime cage? Think about both of these before you start.
Normal Sudoku rules apply.
ARROWS- Numbers on arrows sum to the number in the arrow's pill. Pills are read from left to right or top to bottom.
KILLER CAGES- Numbers in all cages each sum to prime numbers that must be determined by the solver.
KROPKI PAIRS- Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are shown.
Cells with the number 1 and the number 9 are NEVER orthogonally adjacent (share an edge) in the whole puzzle.
