Not having a back button is a big deal. You sit there and think "well, I better just whip out a drawing so I can get back to my list of games" -- the only alternative is to exit back to the homescreen and wait some undetermined time (perhaps for the app to be moved out of memory?)

But the point is that forcing you to play the next turn in the round instead of picking another game acts to perpetuate engagement very effectively.

Yeah, but is it a deal breaker? The comparison is between Draw Something and Words with Friends, which does have a back button, but also a gazillion of users http://www.insidesocialgames.com/2012/01/23/hidden-chronicle... It seems to be a minor detail.

You can force quit the app, and it will relaunch to your list of games.

Heh, which I find myself doing frequently. Every time I get to the point where there are no "easy" choices for words to draw, I find myself force-quitting the app, relaunching, and playing a round with someone different, and then coming back to the round I skipped (incidentally, you get offered new word choices in this case). Hard to say whether having a "back" button would end up discouraging people from continuing the game or not without some A/B testing, and I have a hunch that not having a back button probably keeps people in the game a little longer, but I still wish there was a back button. I'd like to be able to return to the same point in the round instead of having to completely restart the round again.

EDIT: something else occurs to me too. When you are presented with a list of words to draw, you have the option to "bomb" the list and get new words. As I mentioned, if you force quit the app at this point, and come back to that round, you will be offered different words, for free (definitely an exploit if you are patient enough to go through the process of force-quitting and restarting). I guess putting a back button on this screen would pretty much obviate the need for the "bomb" button, and would directly impact their bottom line since people wouldn't have as many opportunities to use their bombs. I have a suspicion that that's the reason there is no back button...the fact that it doesn't give players a chance to back out and keeps them a little more engaged it probably just a happy side effect.

I was frustrated by the new word choices popping up after quitting, actually. I had a pretty awesome drawing, the app crashed, and the new choices were pretty lame.

Minor quibble, I know, but it does seem odd that you get new choices just by quitting when they really want you to pay for them.

Yeah, I was wondering how they would have let something like this slip through. I figure either a) they weren't aware of the exploit (unlikely, but possible...Draw Something, while fun, is not a very polished game), or b) they know of the exploit, but fixing it is a non-trivial. I suspect b) because the game does not appear to store any state between the time you start guessing the other player's drawing, and the time you complete you drawing (so it just starts over if the round is interrupted, as if nothing ever happened). So, in order to remember the list of words that was previously presented to you, the game would have to 1) maintain state that indicates which "phase" of each round you are in for a given game, and 2) maintain the original list of words presented to you after you get to the "choose a word to draw" phase. I suspect they just decided that fixing the exploit isn't worth it, because a lot of iOS users don't even know that they can force quit the app, and a lot of the ones who do probably still wouldn't be bothered to actually do it. Also, having to go through the process of watching/skipping the other player draw his picture again can be tedious.
