How we check the work.
Puzzle generation, independent solving, careful presentation, and correction records are separate steps in our process.
- 01
Generate within a defined brief
Release A is limited to Easy 9 × 9 Sudoku. Candidate puzzles are generated under versioned rules rather than selected from an unrecorded source.
- 02
Verify independently
A separate solver checks that each accepted puzzle has one solution. Technique checks confirm that the Easy collection stays within naked and hidden singles.
- 03
Review the assembled product
Puzzle IDs, answers, page order, exported files, and the nine website samples are checked against their accepted records. Browser samples are separate from the book inventory.
- 04
Publish corrections clearly
Confirmed issues will be recorded on the Help and corrections page. During prelaunch, that page explains what details to keep if something appears wrong.
What this process does not prove
It does not prove physical print quality before a copy is observed, nor does it support claims about health, intelligence, guaranteed learning, buyer preference, awards, or commercial success.
