Simon Tatham's Portable Puzzle Collection
If you like these puzzles, consider giving Nikoli some money, as they are a relatively small Japanese puzzle magazine and invented many of them. I find their handmade puzzles a lot more fun than the autogenerated ones this program makes.<p><a href="https://www.nikoli.co.jp/en/puzzles/" rel="nofollow">https://www.nikoli.co.jp/en/puzzles/</a><p><a href="https://nikolibookshop.stores.jp/" rel="nofollow">https://nikolibookshop.stores.jp/</a><p>I recommend 'The Pencil Puzzle 2022' (and other years) which has puzzles from their entire range. English instructions are included.<p>My absolute favourite is Slitherlink. I've never been more addicted to a puzzle game than the DS version: <a href="https://www.eurogamer.net/puzzle-series-vol-5-slitherlink-review" rel="nofollow">https://www.eurogamer.net/puzzle-series-vol-5-slitherlink-re...</a>
