Good job! That’s really good! Oh damn I didn’t realised it was you!

Dear HN community, susam built the GuessMyRGB game which was a huge inspiration for this game. Please take the time to play it!!

Odd, I only got one wrong, and it gave me a 10/20 score at the end. Is the scoring not 1-to-1?

edit: Oh, I see. Once you get one wrong the game ends immediately, but the score includes the full 20 rounds that you're supposed to get through.

I’m so confused. This is something people know? I mean, I can work it out from first principles knowing how color mixing works, but it sounds like people just … know them? I’ve been programming for almost 40 years and it would never have occurred to me to memorize this sort of thing.

I’d say this is firmly about knowing how colour mixing works, and not about memorising.

Couldn't get above 3 for numerous tries, after 5 minutes or so managed to get to 18! I learned a lot playing this (and reflected on things I already "knew" but never reflected on why). Thanks!
