How To Solve a Kakuro
The numbers given in a Kakuro are like clues. Each is a total to a sum and you have to work out which numbers add up to the total to ﬁll the blank squares. Sounds easy, but each answer has to ﬁt in with the other sums around it.
• Only the numbers 1 to 9 can be used.
• Each number can only be used once in each sum.
• Some combinations have only one solution. They are called UNIQUE BLOCKS. Use the Unique blocks to help you solve the puzzle.
For example a total of 4 for 2 squares is a UNIQUE BLOCK. The two squares can only be 1 or 3, though you don’t know in what order the 1 and 3 go until you look at the other sums around them. Similarly a total of 24 in 3 squares can only be 7, 8 and 9.
