DAY 167:

Today’s Challenge

The rules of Kakuro are very simple.

Just like a crossword, fill in the boxes. Each box must contain a number from 1-9. Each run of boxes must add up to the total shown on the left or above.  You cannot use the same digit in each run, so if a total of 4 is to be completed in 2 boxes, they must be made up of either 3+1 or 1+3, but not 2+2.

Try this beginner puzzle:
