We had a scheduled emergency power outage in my community a few days ago. My battery-backup kept the Internet going for a couple of hours. After that, I decided to move into a room with a bit of natural light and solve cuboids. I solved the cuboids in the order shown in the picture, from left to right:

MF8/TomZ 3x4x5
Calvin/TomZ 4x4x6
Ayi 4x4x5
C4U 3x3x4
LanLan 3x3x2
C4U 3x3x5

I chose cuboids because I know the algorithms quite well and would not have to look at notes on my iPad. That and they are fun. The power came back on as I was looking for my C4U 3x3x7 to solve.

What puzzles would you like to solve if the power went out for a few hours?

Lights out

Mirror cube because you can do it with zero light. It's quite fun.

I'd go for an unstickered Megatwist for the same reason as the Mirror Blocks. The shapeshifting doesn't need any lights.

Another fun challenge would be to unjumble a Helicopter Cube in the dark.

If you want to impress people, Rubik’s Icon Cube. It can be hard to differentiate colors in proper light, the dark would be a nightmare.

Golden Cube of course. BTW I have never heard (read) the term "power outage" before. We would say "power cut".

Ah if only I could get a white golden cube for a small sum ...and I quite enjoy learning about cultural differences even with something as small as dialect

I think it would depend on the day haha, right know though, I would say my 2x2-8x8 puzzles, and then the Minx family.

Peter's Black Hole!
