In the example above, the yellow vertical cells only accept values equal to 7 or higher.

A: Yes, Kakuro and Killer Sudoku are popular puzzles that offer a unique and challenging twist to traditional Sudoku and logic puzzles. Make small pencilmarks noting which numbers are allowed in the empty squares. This will help narrow down possibilities later on.

Some shaded boxes have diagonal lines across the middle to create 2 triangles. A clue will appear in the top right triangle (above the diagonal line) or in the bottom left triangle (below the diagonal line). Horizontal clues always appear in the top right triangle. Vertical clues always appear in the bottom left triangle. For example, 1 horizontal column might have a total 6 boxes. 3 of the boxes could be blank and 3 could be shaded. You can enter numbers in the blank boxes only. The shaded boxes break the column into separate chunks. As well as being useful for solving Kakuro puzzles, exactly the same principles also apply to Killer Sudoku puzzles too, so the same combinations can also be used there. Forexample, the clue 7 in three squares is given as 1.2.4 which means that's the only solution (the "no repeats" rule forbids others like 2.2.3 and 1.3.3). The clue 12 in four squares is given as " 1 to 6", which means it definitely contains a 1 but no numbers above 6, whereas clue 18 in four squares is just given as "any" - more clues are needed! On the board above, the horizontal yellow squares can be written as 6 = 1 + 5 or 6 = 2 + 4. The vertical yellow sum can only be written as 29 = 5 + 7 + 8 + 9.A: Killer Sudoku is a variation of Sudoku that combines elements of Sudoku and Kakuro, where numbers in cages must add up to given sums without repeating digits. Do not write numbers in the shaded cells. The shaded boxes remain empty for the entire game. They break up the columns and rows into smaller “chunks” to create more space for gameplay on the board. The “clues” appear in the shaded boxes only. Any completely blank box is yours to work with. [3] X Research source
Use pencilmarks to note which numbers are allowed in the empty squares. This will help narrow down possibilities later on. There is one other rule, to make it easier. Within each clue, you can't have the same number more than once. So for example that clue of 12 couldn't be 6, 6 because that repeats a number. The numbers can appear in other clues though, of course, it's only within a clue that numbers can't be repeated. How to solve Kakuro puzzles For the yellow cells highlighted above, there's only one way of writing the sum: 4 = 1 + 3. However we still need to figure out which permutation (1 + 3 or 3 + 1) to use. Kakuro are easy to learn yet highly addictive language-independent logic puzzles now following the footsteps of the worldwide Sudoku success. Requiring just pure logic and simple add/subtract calculations, these numerical-crossword puzzles will carry you into a fascinating world of number combinations you never imagined could exist.

The tables below list the possibilities for all lengths of clues, with the bold entries showing the unique solutions for that clue.
