Welcome to this KenKen® Solver
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.
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

correctly it can be solved.
