Kenduko

Multi-killer

The Kenduko and Multi Killer puzzles are hand crafted Sudoku style puzzles that require some arithmetic to solve. The solution is the same as a classic 9x9 Sudoku. The Kenduko puzzle is a combination of the LatinCalc & Killer Sudoku puzzles. As in a Killer Sudoku, a "Total" is included at the top left of some (not necessarily all) of the fenced areas. However, there is also an operator (+, -, or ). The "Total" is calculated by using the operator on all the numbers within the fenced area. In the case of Kenduko, numbers CAN be repeated within a fenced area. The Multi Killer is simply a Kenduko where only multiplication is used. A Multi Killer can also be defined as a Killer Sudoku in which multiplication rather than addition must be used to calculate the totals. Once again, the Multi Killer puzzle CAN have numbers repeated within a fenced area. The multiplication signs ( ) are included in the Multi Killer puzzles to distinguish them from a Killer Sudoku. These puzzles would be ideal for use in Sudoku competitions or tournaments to further stretch the talents of the competitors.

The Kenduko & Multi Killer puzzler are also available as "X" type puzzles. The "X" puzzles have an additional constraint. All the numbers, 1-9, must appear in each diagonal. This will, usually, produce an easier puzzle. The example below, however, is a Kenduko-X puzzle with only 14 clues and would be classed as Expert grade.

To identify an "X" puzzle, the diagonals are shaded.

Both Kenduko and Multi Killer puzzles are also available as overlapping Samurai and Ninjo puzzles as required. Due to the size of the puzzles, both Samurai & Ninjo  versions require large format printing, or breaking into smaller pieces, to be able to solve them.
