## The Rules

All the digits 1 to 6 must appear in every row and column. In each coloured block (or 'cage'), the target number in the small board above is calculated from the digits in all the cells in the block, using the operation indicated.

## Welcome to this KenKen® Solver

This is a Beta demonstration version exclusively for www.KenKen.com feedback.

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 KenKen puzzle using the new 'designer' - click on "Enter new KenKen". 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.
