How to play Kakuro at Kakurolive
The goal of the game is to fill all the white cells using the digits 1 to 9.
the black cells contain hints – the number in the black cell is the sum of the block of white cells associated with it
we’ll start in the upper left side. the number 4 which is in the upper right section of the black cell is the sum of the horizontal block of white cells associated with it.
the block has 2 cells and 3+1=4.
the number 3 which is in the lower left section of the black cell is the sum of the vertical block of white cells associated with it.
the block has 2 cells and 1+2=3
you cannot user the same digit twice in the same block!
Therefore this 3 cannot be {2,1}
it has to be {1,2}
which makes this 3 to be {1,2}
and if you put 5 in the middle it’ll all fit – 8=2+5+1 and 9 = 3+5+1.
Kakuro has unique combinations and it’s easy to start the game searching for them. for example:
in 3 cells, the sum 6 has to be the digits {1,2,3} the sum 24 has to be {7,8,9}, you still have to determine the order of the digits in the block.
