Cage Combinations
|
Killer Sudoku is a fiendish variant of Sudoku - the same 9 x 9 board with rows,
columns and nine boxes that must be filled in with all the numbers 1 to 9. But
instead of seeing some starter clues where some cells are completed for you, in
killer sudoku areas of the grid are "caged". Each cage contains a single number
which is the sum of all the solutions in that shape. You have to use this
information to crack the Sudoku, but all the normal strategies of Sudoku still
apply.
Anyone who has tried Kakuro will see a connection. A cage of two
cells containing a target of 3 will must contain cells with the value 1 and 2.
(We conform to the Killer convention that no cage will contain a duplicate
number even if it is within the rules of sudoku).
Killers strategies are explained on our forum here and on this external site
here.
A list of Cage/Value combinations is available here.
