For organisations
What is on offer
This Sudoku can be embedded in an institutional, educational or internal service, or delivered white-labelled. It was built with accessibility as a requirement rather than an afterthought.
What exists today
- Korean and English, each at its own address
- A complete keyboard path — arrow movement, digit entry, candidate marks, undo
- A grid structure and announcements written for screen readers
- State shown by more than colour alone (conflicts, completion, evidence highlighting)
- WCAG contrast held by an automated check (4.5:1 text, 3:1 non-text)
- Puzzles built per request and verified to have exactly one solution
- Five difficulties, a timed mode, and a technique-practice mode
- No accounts and no server-side storage, so the data surface is small
Possible shapes
- Embedding — the game inside an existing site or app
- White label — a separate deployment with colours, wording and languages to suit
- Puzzle supply — the generation API, or batches for print and publishing
- An accessibility review of an existing puzzle service
What does not exist
There are no accounts, no server-side progress, no payments and no multi-user features. If you need them, the requirements come first and the discussion second.
Difficulty is based on clue-count bands and is not claimed to match perceived human difficulty exactly. Publishing work that needs graded difficulty would need separate analysis.
