Undo button for 2048

[calhix]

I'm a huge 2048 fan and use the back button a lot when playing on my phone/tablet! This would be a nice addition I think, though perhaps a bit subjective.

Could you describe that a little more? I have absolutely no idea what you mean.

Sure, at least with the app I use (https://play.google.com/store/apps/details?id=com.tpcstld.twozerogame&hl=en_US&gl=US), this has a back button on the top right of the screen that's to the left restart button, you can see it in the first picture to the right of the video. It's nice if you swipe the wrong way or if two swipes are registered when you only meant to do it once. I think most of the 2048 apps I've used has it as an option (I've probably tried more than 5 of them) but I know one or two of the ones I've used in the past don't.

Ah. I was confused because you call the game once "2s" and once "2048". And I was wondering how a back button for two seconds cold be helpful.
You should stick to one name. And maybe call it "undo" instead of "back", that would be crystal clear.

Ah, the reason for the name change is I thought the game is named "2s" on the watch and it's called 2048 everywhere else, I said 2048 to clarify in the post I was talking about the game on other devices, didn't even cross my mind for some reason that 2s could be considered 2 seconds.

There's not really space to put an undo button on the screen. How would the undo feature be accessed?

I've been thinking that this could be done with a double-tap gesture, what do you think?
