KenKen Dog Legs
From sudokuwiki.org, the puzzle solver's site
|the key difference between KenKen and KenDoku is that KenKen only requires unique solutions across the whole row and column - whereas KenDoku is much more like Sudoku - the boxes must also be 1 to n. So in this example of a KenKen puzzle, we have a greater number of chances that a cage of more than two cells will contain combinations with duplicate numbers.
The 4x is a simple one where the duplicates must be placed diagonally from each other. However we don't know if they must be two 2s or two 1s.
The 36x contains combinations with duplicates and one without. It will be the solvers task to decide which is right.
To contrast these, the simple two cell cages such as the 6x highlighted can't contain combinations with duplicates. Therefore the hoever over on the solver is a different colour.
