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
"
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.
New: Version 2.37.4 (9th Jul 2025)
Fixed a bug that prevented puzzle imported from the two part strings
from clearing the old board. Cage/Unit strategy detection got a boost.
New: Version 2.37.3 (8th Jul 2025)
Completely new killer puzzle entry system. Two steps:
Use your mouse to click and drag a set of cells into a cage. Much quicker than clicking on the borders.
Then change to "clue setting" mode to enter clues.
