Show HN: Tiny logic and number games I built for my kids

I’ve been building a few small games to help kids (and curious adults) build reasoning and logic skills. Think Word Ladder, Prime Hunter, Math Maze ,all in the browser, no installs. Would love feedback or suggestions for new types of puzzles

Prime Hunter sometimes generates sets with no prime numbers.

This is really great, well done! I have two young kids and was thinking about putting something like this together and I'm delighted that you beat me to it. Having a 6yo and 8yo, it would be great if there were some more basic games as well.

FYI Firefox fails to load the page for me:

it's really nice (both idea/purpose and execution). what would be really great is having direct URLs for each game so you can share and point your kid to specific puzzle.

I'll just pop in to say it's neat that you built that for your kids. The presentation is good, too.
