Are the puzzles guaranteed to have one solution?

Yes, and it is checked rather than assumed. Every board is run through an independent solver that reports whether the solution is unique; any board that is not uniquely solvable is discarded and regenerated, and the printed answer key is compared against the solver's answer before the page is built.

How difficult is 'hard'?

Hard boards carry fewer givens and need the standard intermediate techniques — pointing pairs, box-line reduction and the like. They are solvable by logic alone; none of them require guessing.

Can I split this into several books?

Yes. Many publishers turn one interior like this into a three-volume series by difficulty. Your licence puts no limit on how many books you make from it or how many copies you sell.

Will another publisher have the same boards?

No. The file is generated when you order, seeded from your order, so your 300 boards are yours.

How many pages is it?

The full page count is listed in the file list above and is exact — it is measured from the rendered PDF, not estimated. Both trims stay inside KDP's 24–828 page range for a black-ink paperback.

Look inside

Building real pages…

Three books' worth of sudoku in one interior: 100 easy, 100 medium and 100 hard, one large-print grid per page, with a complete solutions section. Set for 8.5 × 11 with no bleed in black and white, and included as a 6 × 9 edition too.

Every board is machine-verified twice before it reaches the page. A sudoku that has been dug too far has more than one answer — that is not a hard puzzle, it is a broken one, and it is the complaint most likely to sink a published sudoku book. Each grid here is solved independently, confirmed to have exactly one solution, and checked against the answer key that gets printed.

As with every Line A interior, the file is generated for your order. No other publisher receives your boards.
