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 2.37.2 (3rd Jul 2025)
Completely new killer puzzle entry system. Two modes: Use your mouse to click and drag a set of cells into a cage. Much quicker than clicking on the borders. If you are using an iPad or phone the second input mode is easier.

Added 'innie and outies' taking it from Killer Sudoku.

New: Version 2.34.1 (9th Apr 2025)
Added 'Hints Mode' next to Take Step. Choose between only revealing the next strategy, just the pattern or just the eliminations.

Added Rule of 720 to this solver.

New in version 2.32.1 (13th Mar 2025)

New in version 2.31.8 (2nd Mar 2025)
New algorithm to compute 'dog-leg' combinations. Fixed missing combinations.

New in version 2.31.3 (3rd Feb 2025)

New in version 2.31.2 (31st Jan 2025)
KenKen Parity Strategy now in solver.

New in version 2.29.6 (16th Jan 2025)
