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 :)

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.

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.

Sure, I will take care of it. Thanks for the feedback

Yep, got stuck with this too.
