How the levels work
Each puzzle page shows its level and the trick it needs in plain words first, with the usual puzzle name after it, such as "Only one number fits (naked single), see page 3". Page 3 explains every trick in more detail. Gentle: only one number fits a square. Easy: a number has only one place left in a row, column or box. Medium: a number is locked in one line of a box. Hard: two squares share the same two numbers. A puzzle gets its level only if it can be finished with that trick and cannot be finished with the easier ones alone. No puzzle needs guessing.
Checked
- Every puzzle has exactly one solution, counted with two separate solving programs
- An independent tester re-graded all 10 puzzles with their own solver: 10 of 10 labels match
- The printed solutions match the puzzles square by square, in both files
- Printed marks stay at least 0.58 in (14.9 mm) from every edge, measured on 300 dpi images of all 36 pages
- No colour on any page, so it prints the same on a black-only printer
How to print
Open the file for your paper size and choose "Actual size" or "100%", not "Fit to page". Print the whole set or one page at a time. To keep the answers hidden, print pages 1 to 13 only.
Good to know
- This is a free sampler with 10 puzzles, not a full book.
- We have not test-printed these files on paper yet. They were checked on screen and as 300 dpi page images. If a page does not print well for you, email [email protected] and we will fix it.
- The cover is plain text, without pictures.
- Each puzzle page names its trick in plain words, with the usual puzzle name in brackets; page 3 explains every trick.
