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

This reminds me of the Optiver internship selection process.

Prime Hunter sometimes generates sets with no prime numbers.

Also, tiny nit but the text at the end says the largest known prime number has over 24 million digits. While technically true, the current largest prime number in fact has over 41 million digits!

(Also, I love this. I hope you’re still hosting it once I have kids)

> the current largest prime number in fact has over 41 million digits!

Because there's an infinite number of primes?

I did something similar for my children – very suitable for ages 3 to 5: https://store.steampowered.com/app/3355240/Teach_Kids_Games/

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.

Have to ask: How old are your kids? Very fun puzzles! Do they like them?

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 was trying the sum game, but there was no combination of three numbers to add up to 15. I took a screenshot if it helps.

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