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

Nice work. I like the simple, unobtrusive and ad-free interface. I have kids who could use this although you face lots of competition for their very limited allotted active screen time [1]. The 6 yo gets 45 mins a week on the computer, usually opting for PBSkids, Kodable or Scratch. The 3 yo gets 15 mins usually opting for guided digital canvas painting as she learns to use a mouse.

There are a few good no-screen puzzle books for kids (lookup the ones by Usborne).

As a recent publisher of an interactive children's book [2], I am seeing more sales of the physical books than the digital/web editions despite the latter having more features including an element of teaching math.

Curious if you considered publishing a physical book with these concepts/math puzzles?

the 2nd game, click the prime numbers, my second board had only a 1 as a potential candidate, and 1 is not considered prime. the other numbers were all composites and I was awarded a big fat zero for knowing all this. (I went back in and the game does not allow clicking the 1, good; but the description "divisible only by 1 and themselves" doesn't really rule it out. maybe don't give 1's or explain this)

clicking the prime numbers is a bit hard to do, and they scooch out of the viewing area and disappear for a bit. not complaining but while i was figuring out the game on my first board, I did terribly because of that.

given the level of math proficiency required for the prime number game, I was shocked in the next math grid game when using the ascend/descend buttons it simply told me every time I had hit the right answer. thought this was how to play so I didn't try typing numbers in. on my firefox browswer the answer numbers are too big to fit in the cells.

It's cute! Well done. I enjoyed playing them.

The Math Grid game can be "solved" by just clicking the increment/decrement buttons until the outline of the box turns green.

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

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.

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.

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

This reminds me of the Optiver internship selection process.

FYI Firefox fails to load the page for me:

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.
