Long ago, I placed a stickerless Dayan Megaminx (a dodecahedron shaped puzzle) on my list and forgot about it. I had no real interest in it, had no expectation of ever being able to solve it (I was a 2-minute 3×3 solver at the time), and, more than anything, thought it would be a funny item for the wishlist. Lo and behold, it arrived at my house last December. I messed with a few times, got frustrated, and stashed it on my shelf.

A couple days ago, my 19-month-old brought it over to me, having scrambled it on his way. My OCD thusly challenged, solve it I had to. Which meant learning how to solve it.

I experimented a couple times and then, on my third, decided to give it a go on video. Here is the result — a 10-minute solve (excluding the last layer), presented at 3x speed: Continue reading
