I was pretty sure that I got a 25th Anniversary Rubik's Cube, with one reflective silver side instead of the white side sometime after my older child was born. He's only 13 now, and 25+13=38. So, how did we get to Google's posting of the 40th Anniversary of the Rubik's Cube as a Google Doodle?
Well, you have to change the goalposts a little. The 25th Anniversary cube came out in 2005, which is 25 years after the 1980 Ideal Toy Company product release, and the 30th Anniversary wooden cube came out in 2010. Those two things are still on the same timeline. However, if you look at when Ernő Rubik actually built a working prototype of the cube, that was in 1974, which is 40 years ago.
Like most Google Doodles, it's well-constructed, but I tried not to take too much magic out of it to see if there were keyboard shortcuts. You do get a nifty screen for solving, which honestly I wasn't sure was going to happen or not.
I had thought about shooting some cube video for this evening, but I think the surprise of the finish screen is fun enough.
