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?

[1] This app inspires me to upgrade some of their passive screen time (TV) to more of your and similar apps

Prime Hunter sometimes generates sets with no prime numbers.

I can confirm this bug - your random number generation algorithm should ensure at least one prime appears in each set, perhaps by maintaining a pre-computed list of primes within your range and guaranteeing inclusion of at least one.

In the few games I tried, it always ended up that way. You start with a few prime numbers (if you're lucky). Each time you click on one, it gets replaced with another number that usually isn't prime. After a short while, there are no primes left and then there's nothing to do but sit and wait for the game to end.

Perhaps all the numbers should have a finite lifetime, after which they evaporate and a random new one replaces them.

Or maybe right click to identify a number as composite.

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?

*largest known :)

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

Leaving the web environment makes stuff like this more exciting to me - is this Unity or Godot? Would love to learn Godot but have a hard time.

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 found that when no more prime number, the game still on. When I clicked non prime number game over and showed my score.

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.

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.

Likewise on the prime number game, I had a board with all even numbers >2.

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.

FYI Firefox fails to load the page for me:

> Secure Connection Failed > > An error occurred during a connection to quizmathgenius.com. Cannot communicate securely with peer: no common encryption algorithm(s). > > Error code: SSL_ERROR_NO_CYPHER_OVERLAP

Same for me.

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

nice work! But these arent that easy! What age group target was this for?

This is great. I've been working on a social site where the content users post and scroll through are microgames (<500kb). My kids are my biggest users so far. My daughter loves this pill sorting game, for example:

This reminds me of the Optiver internship selection process.

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.
