KenDoku Dog Legs
From sudokuwiki.org, the puzzle solver's site
|In this example, the first KenDoku in the solver examples, some cages are indicated with their respective combinations. The easiest is the 9x which can only be 1 x 3 x 3. But because this cage spans two boxes we can instantly place the two 3s and the 1. Placing them diagonally apart will mean the 3s don't conflict with each other. The one number per row, column and box is preserved.
The more complate 12+ has five possible combinations. Two of them are highlighted to show they contain duplicates.
The last cage indicated shows a 'dog leg' 3-cell cage with 9+. However, since it is entirely contained within a single box no duplicates can exist. Three combinations are possible.
