Kakuro Tips

The best way to solve a Kakuro, like Sudoku, is to use logic. Although you could use brute-force guessing it rids the puzzle of most of its enjoyment. Start by looking for a clue that have the fewest possible combination of numbers, usually those with 2 or 3 squares. i.e. a 2 square clue which totals 3 can only consist of a 1 and a 2. In the below chart we can see how this helps us:

 
   
4  
 
  3
   
   
     

The only 1 combos for "3" are 1 & 2. The only combo for "4" is 1 & 3 (as we can't repeat numbers in an answer it can't be 2 & 2). Therefore the intersection must be 1, the only number they both have in common:

 
   
4  
 
  3
   
1  
     

This means we can slot in the remaning numbers and hopefully this would help us fill in some more numbers in a real puzzle.

 
   
4  
 
  3
   
1 2
  3  

See the charts below for a guide to number combinations.

Also as in Sudoku it may be useful to mark potential values for cells in the corner until you can reduce this to one value. This is usually called “pencil marks” and is used more in the more complex puzzles.
