12x12 Kakuro Puzzles

The 12x12 kakuro is the biggest kakuro here, packed onto a single page. Its longest runs hold eight cells, which means each of them misses exactly one digit from 1 to 9: subtract the clue from 45 and you know which.

Easy, Medium and Hard versions are available, and reasoning alone leads to the one solution of each. They suit solvers who already enjoy the 10x10 grids and want more crossings to chain together.

The 45 Rule for Long Runs

The nine digits total 45. An eight-cell run therefore leaves out the digit equal to 45 minus its clue: a clue of 40 means the 5 is missing. On a 12x12 grid, those runs are the backbone of the solve, and their crossings with short runs settle the first digits.

Keeping Track on a Big Grid

With so many runs, candidates matter. Note the possible digits of each crossing in small figures, and cross them out as runs close. A Hard grid sometimes needs a whole run tried in your head, so a clean page pays off.

For Experienced Solvers

Start at Easy even if you know kakuro well: the size alone makes a 12x12 grid a challenge. At Hard, whole runs must be weighed before a digit is certain, and each grid still has one logical solution.

Frequently Asked Questions

Is the 12x12 grid too small on A4 paper?

No: one grid fills the page, and its cells stay large enough for digits and small pencil marks. That is also why this size has no four-per-page sheets.

Which digit is missing from an eight-cell run?

The one equal to 45 minus the clue, since the nine digits add up to 45. A run of eight cells with the clue 44, for example, holds every digit except 1.
