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)

Man I really need to learn Crystal. I love the ruby syntax and it's supposed to be really fast right?

Yeah, it's still a very small language, not much community or tooling, but a pleasure to use. In practice it'll hit half the speeds of low level languages like rust and C, but with way less effort.
