Hyperbolica, game dedicated to Non-Euclidean geometry just released on Steam for pi day!

I'm in Matt Parker's π day video as part of the team failing to reproduce local hero William Shanks's by-hand approximation of π: youtube.com/watch?v=dtiLxLrzjO

Just curious, how many digits of π do you have memorized?

Honestly I haven't really bothered going beyond 9 significant digits (3.14159265) since I doubt any manual estimate calculations I have to do involving π would need further precision, plus I know this truncation is rounded off properly (the next truncation that's also rounded off is 3.141592653589793, an extra 7 digits to tackle)

Chanced upon this #piano album full of pieces inspired by π, released for #PiDay2022:

So I know people have talked about optimal first guesses in , but are there optimal first guesses for ?

Maybe someone can generate all the 8-token equations that comply with Nerdle's rules and perform some info theory analysis on them

Random idea for a game (partially inspired by ):

Give the player a limited number of guesses to figure out a mystery finite set of integers $$S=\{n_1,\ldots,n_k\}$$, given $$k = |S|$$ and hint indicators for each guess $$S_j$$:

- for each $$n_i\in S$$, whether $$n_i \in S_j$$;
- if all $$n_i \in S_j$$, whether $$S=S_j$$ or $$S\subsetneq S_j$$

Prior non-final guesses could be infinite sets to whittle down the possibilities, e.g. $$\{3n:n\in\mathbb{Z}\}$$
