Sites we recommend
A short list of sites we point readers towards when they ask for more — places with real depth in puzzles, learning, or care for older adults. These are the ones we go back to ourselves. Nobody paid us to mention them and nobody paid to appear here; this is just stuff we genuinely like.
Maths Is Fun
Long-running general-maths and puzzle hub from the UK. The puzzle section is broad, the explanations are clear, and it's one of the few sites that does both teach-the-concept and let-you-play under one roof. Good first stop for anyone who wants the maths context behind the puzzles.
Visit site →Math = Love (Sarah Carter)
Sarah Carter's classroom-puzzle blog. Written for maths teachers but useful for anyone who learns better from worked examples. Her Sudoku-variants posts pair well with our glossary when you want to dig further into a specific pattern.
Visit site →123 Homeschool 4 Me
Comprehensive free-printables hub for homeschooling families. Their seasonal Sudoku posts are how a lot of kids first meet the puzzle. If you're after activities that cover more than just Sudoku, this is the place to go.
Visit site →The Imagination Tree
Anna Ranson's UK creative-play blog. Aimed at parents of younger children. We point readers here when the conversation drifts towards 'screen-free quiet activities for after school' and a Sudoku grid alone is too narrow.
Visit site →Living Montessori Now
Montessori-flavoured education blog. We point readers here when they ask about logic-puzzle work for younger children — the framing of Sudoku as a focused-attention activity rather than a puzzle game pairs well with Montessori practice.
Visit site →Memory Matters
Plymouth-based dementia charity offering free activity sheets designed for cognitive stimulation. We feature them because their materials are written by people who know the audience, not generated to fill SEO pages. The right starting point if you're caring for someone with dementia.
Visit site →Activity Directors Network
Long-standing community for activity directors in nursing homes and assisted-living facilities. The forums and downloads section are a real working library for people planning daily activities for older adults.
Visit site →MathPuzzle.com (Ed Pegg)
Ed Pegg Jr's recreational-mathematics site. Niche, slightly old-school, frequently updated, and the kind of place where the comment threads are worth reading. For the solver who wants to follow puzzles past Sudoku into the wider world of recreational maths.
Visit site →Conceptis Puzzles
Puzzle publisher whose technique pages are some of the best on the web — particularly their walkthroughs of Sudoku variants. If our glossary entry on a technique leaves you wanting more, theirs is the natural next click.
Visit site →Krazydad
The reference free-printables hub. If you've ever printed a Sudoku from somewhere on the internet, there's a real chance it came from here. Especially good for variant fans — the Killer Sudoku and Inkies sections are deep.
