I host a Shell Challenge each month from my discord and Twitch channels. I need to be better about promoting them, however, so that’s what this section is for. Every first or second Wednesday of the month is tour night, and I tour everyone’s submissions on this night. If you cannot attend (or don’t get done in time for the deadline), I am more than happy to tour any completed shell challenge for free at any time you are able to stop by a sims stream on my Twitch channel.
That being said, this section is also all about having a record of all the shell challenges I’ve done in the past. I have, from very early on, always tried to make each of my shell challenges be a bit of a brain-teaser. Something that will make you think. Either with a theme, or a puzzle/problem, or coming up with a story in your head to match your build. I am perpetually coming up with new ideas, so don’t expect these challenges to stop anytime soon – I have at least through 2024 and most of 2025 already either planned, or the ideas sketched out. In some cases, they’re already even built and ready to go except for their promo graphics.
