- Plain black type on white is the most readable pairing at this size.
- One file prints whole on Letter or A4 — choose paper, change nothing else.
FAQ
Frequently asked questions
- Can a hard puzzle really be printed this large?
- It can — difficulty comes from how few clues are given, not from cramped type. These grids start with fewer numbers than the easy and medium packs while still printing at the full 43pt tier.
- How does the hard level compare with the 36pt hard pack?
- The puzzles are calibrated the same way — only the type size differs. This pack prints one 43pt grid per page for 30 puzzles; the 36pt large print pack offers 50 at a slightly smaller size.
- Is the difficulty technique-graded?
- No — like every sudoku on this site, hard is a calibrated label based on clue count and generation, not a measure of which solving techniques a grid demands.
- How many clues do these hard grids start with?
- Around 27 to 29 of the 81 cells, printed above each puzzle as “Clues: N.” That is fewer than the easy and medium tiers, which is what makes the solve tougher.
