Nice site. I assume vibecoded but it was tasteful and performant on mobile. Thanks for open sourcing it

I "Lost" to Jev while getting 10/10 questions and it got 8/10. Interesting scoring?

I wonder if they fixed it, or if it depends on the game type. In Versus mode, I got 10/10, Jev got 7/10, but the points were closer: 1201 to 1034 so I assume time is also part of the calculation. One of mine was 9.6 seconds vs 0.3 seconds. It wasn't always clear where you were supposed to click, like on a graph, the choices were buttons at the bottom of the screen.

Very cool demo! Although I feel that incorrect answers should be penalized more. For instance- I got 100% in about 45 seconds on the sprint. Then, I clicked through as fast as I can (only limited by finding the right targets) and got a score of 42s, technically better than my first score but I only got 20% right.

Thanks for the feedback! And now that you showed everyone a cheat sheet we will get many high scores, so lets increase the penalty of wrong answers and reset the leaderboard! Thanks a lot for the insights

Could you add an option to remove musical theory questions? I mean, I know Jev can ace those as well, but I can only click at random, that's unfun

just play again :), but will consider adding whitelist/blacklist of categories

also less USification would help, it's not common knowledge how US birds or bridges or hats look like

Would prefer if the audio button was at the top right of the page etc.

Will take a look, should already be there during a game though

The first one I opened only gave me a single option to press and when I pressed it the app told me I was wrong and that Jev had pressed the correct button (which was invisible to me I guess?)

I saw several other questions where I pressed the right answer and the app scored me as wrong. Broken slop.

I got a lot of answers wrong (half of them maybe?), and the ones I got it right Jev was still faster.

Play some more you will get the hang of it :) The first 200 cards I did: Jev got 160 right, at a median of 261 ms , so no need to feel bad

Interesting. Jev is certainly faster but it was wrong quite a bit more than I was.

I thought I did terrible 5, but jev got 0 in a row. then the slopcoded app says "Jev has won 2,613 of 3,300 games, this one included."

Though if you need very quick answers obviously humans can't compete.

Actually on further thought after getting 15, if you've seen the exact problem before you can answer quickly, so the usefulness is diminished to problems that don't need to be 100% correct, need to be solved very quickly (even routing might not need to be this quick), problem form often changes, but is still general knowledge, and very low marginal benifet for 99% correctness over 50%
