Day 2: Cube Conundrum

Megathread guidelines

Keep top level comments as only solutions, if you want to say something other than a solution put it in a new post. (replies to comments can be whatever)
Code block support is not fully rolled out yet but likely will be in the middle of the event. Try to share solutions as both code blocks and using something such as https://topaz.github.io/paste/ or pastebin (code blocks to future proof it for when 0.19 comes out and since code blocks currently function in some apps and some instances as well if they are running a 0.19 beta)

Is anyone else like me, but it took me longer to understand what I was supposed to do on day 2 than on day 1? However, here is my solution written in Golang: https://github.com/alexruf/adventofcode2023/tree/main/d02

It was confusing. It took me 3 tries to write the parser. The first time I didn’t realize there were multiple observations per game and the second time for some reason I was convinced the color came first.
