What is on this page

Thirty classic 9 by 9 boards are generated around 33 starting numbers, the middle point between the 42-clue easy set and the 26-clue hard one. The engine removes a clue only when the remaining grid still has one solution.

How to choose a printable

Choose any card: every puzzle is the same medium tier but a different deterministic board. If the first few numbers do not appear by scanning, write small candidates rather than guessing; the separate answer page is for checking the finish.

What the files contain

Every card downloads one language-specific PDF. The puzzle or activity comes first and, when there is an answer, the completed solution is the last page of that same file. Each footer names the collection and the exact sheet, so pages from a printed stack can be matched again.
