Quick help: Using this Solver

You can pick examples from the list above. Click on Take Step to step through the solution. Unknown squares are filled with 'candidates' - possible solutions.
Any cells that are reduced to one possible candidate are solved.

You can enter a new Sumoku puzzle using the new 'designer' - click on "Enter new Sumoku". Once you fill in the clues and set up the cages correctly it can be solved.

Unlike the other solvers you can only edit the main board when solving. The small board only displays the clues.

How to play Sumoku

Sumoku is a hybrid between Killer Sudoku and KenKen.
Like KenKen there are no 3x3 boxes (a third constraint).
Like Killer Sudoku the cages are always summed (addition).

You need to place the numbers 1 to 9 on all the cell so that 1 to 9 is unique in every row and column like a Latin Square. However, you will have few, if any, completed cells in Sumoku. Instead, groups of cells form blocks or 'cages' - and the clue is the sum of the solutions to those squares. Each 'cage' is shown by a color or dashed line. A clue of '3' in a two-cell cage means those cells will contain 1 and 2 - but it won't be obvious which way round at the start of the puzzle.

This puzzles follows the Killer Cage Convention which says duplicate values are not permitted in a cage.

Combinations are key to this puzzle at the outset, but all Sudoku strategies still apply. Killer specific strategies have been highlighted in cyan in the strategy list.

I'd love to hear your feedback.
