Kakuro is superb for improving people’s number combination skills. Follow the rules and have a go at this simple challenge:
- Just like a crossword, fill in the boxes,
- Each box must contain a number from 1-9 and each run of boxes must add up to the total shown on the left or above,
- Digits cannot be repeated in each run, so if a total of 4 is to be completed in 2 boxes, this must be made up of either 3+1 or 1+3, but not 2+2.
Here is today’s Kakuro puzzle:
