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

+ Put all apps and books under one umbrella brand. Your book doesn't have a unique name associated with it. Little Math Genius or Little Math Whiz, for example.
+ Setup an umbrella website (littlemathwhiz dot com) and blog
+ Start aggregating a user mailing list where you can provide gentle updates (beta test new features on quizmathgenius, new book announcement etc)
Perhaps all the numbers should have a finite lifetime, after which they evaporate and a random new one replaces them.
(Also, I love this. I hope you’re still hosting it once I have kids)
Because there's an infinite number of primes?
Path finding in a 16x16 grid is also another great demonstration of BFS and DFS.
Using derivatives to make a targeting system and animating the result is another cool mathematical experiment.

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.

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