Same issue. I'm on the latest version of Chrome (mac). Edit: Oops... just saw the reason why.

Mind sharing the reason?

I would implore anyone who's thinking about playing with a Rubik's Cube to not read any of those "how to solve it quickly" things. It may have taken me a year of chipping away at it and my process is definitely suboptimal, but at least I have the satisfaction of having worked it out myself. Also, play with it! It's an incredibly simple but totally mind bending device.

I would encourage a hybrid approach if you are getting nowhere. There is a trick to finding solving patterns known as commutators. For instance, see http://w.astro.berkeley.edu/~converse/rubiks.php?id1=basics&... Once you learn the basic idea of the commutator, you can easily make up you own system. Essentially you select a part of the cube and make some specific change to it. For instance, you come up with a move se…

:) that was pretty much my approach.

The way I attacked it (and suspect people naturally would) was a layer at a time. When you're doing that you try to preserve what you've already solved.

Once you have 2 layers sorted and you're trying to do that last one there's not much room to manoeuvre. I spent countless hours coming up with a combination that preserved my top 2 layers and following where each individual piece moved in the final layer. If nothing else, it's great for memory and spatial awareness.

If you want to get a cube to muck around with, don't frustrate yourself with something default - either pull apart and lubricate one of the standard ones, or pay a little bit more and get something used by at least keen amateurs. The cheap ones are pretty miserable to use. I have one of these and it's smooth: http://lubixcube.com/lubix_dayan_guhong_v1.html Bad Mephisto has already been linked elsewhere - he has some…

I highly recommend any cube from Dayan, but this is my favorite: http://www.amazon.com/dp/B008U6V50U It's smooth as butter, and there are no stickers to cheat with.

Stickerless cubes were until very recently illegal in competitions. The new regulations (in effect from July 2015) allow these now, meaning a stickerless Zhanchi is a really good purchase.
