Essentially correct! Instead of `1 None` it'd fail with a `KeyError`. You can get a probability distribution too: 1 baz 1/8 KeyError 1/8 2 foo 1/8 2 bar 1/4 2 baz 3/8

Here's a cute follow-up: what are all possible outputs of the following program? import random class C: def __hash__(self): # return 0 or 1, with equal probability return random.ra…

Hmm that might be a good idea! The point system is supposed to normalize difficulty, but I understand people might skip the egregiously long ones anyways.

Thanks for all the feedback! 1. Hmm, perhaps we could change the game model? Instead of solving as many as you can in three minutes, we could (1) have a set time per problem, and a…

Supporting custom macros seems hard, but we should be able to fix spacing problems if we revamp the comparison logic entirely. Thanks for filing the Github issues -- we definitely …

Some people have gotten above 90, but I haven't broken 60. :'(

Thanks for the feedback! In fact, you can even do stuff like $\binom nk$ or $\frac 1n$, you don't need the space.

Weird...before the 3-minute limit? Maybe there's a bug somewhere with the timer.

1. That's why we added a point system, but I agree the variation in difficulty is pretty wild. 2. See my comment above - comparison is a tough problem right now, the website is pre…

Tutorial mode is a great idea! Yeah, this is definitely geared towards experienced people.

Yeah, the comparison logic is pretty simple right now (see my comment). Unfortunately, `\not\in` and `\notin` look slightly different. We're figuring out the best way to accept sli…

One of the developers here! Right now, we compare answers visually, so for example `n \choose k` and `\binom{n}{k}` will both be accepted. However, sometimes there are things that …
