Rubik's Cubes

Japan's prime minister Abe declared a state of emergency last month. However, we cannot complain the inconvenience because Japan is not under lockdown or quarantine. We are allowed to go out with some caution, such as social distancing and wearing a mask.

It is how to spend during staying home that matters. My elder son, Yuto, and I bought Rubik's Cube and its variations to kill times. I do not think that this would be the best strategy, though.

I am really proud of solving all the 12 puzzles. Of course, some were too hard to solve without instructions which were easily found online.

We decided to get another set including four cubes. We are looking forward to trying them although it has been already overdue to the scheduled arrival date.

P.S.
I have been able to solve the standard one, 3x3x3 Rubik's Cube, since I was in elementary school.
