Watch the Playthroughs

Every week, I select a daily puzzle from that week and record my own playthrough, where I describe my thought process, make progress, and solve the board. I don't do any prep or review before I start, which means that I myself don't know how things will turn out until the end of the video.

You can also watch this video, and past playthroughs, directly via my channel on YouTube, which also features Hexakai speedruns, logic and math puzzles, and other great content!
