just figured out kind of a hack for this game. i'm not sure if i like being able to do this...
if you swipe twice, really fast, you can prevent blocks from popping up where you don't want them to. for instance, if you have all your big numbers in one vertical row down the right side, and you have no choice but to swipe left (which will likely ruin your game), you can swipe left and then swipe right very quickly...and no block will pop up on the right side of the screen.
Blech, I think the latest update fixed the hack where you can move twice quickly and control where the numbers drop. Looks like I'm done with this game. Can't see how I'll make it to 4096 without that.
what is the strategy? I generally funnel everything to the lower left corner and have my biggest number there and try to work top down, but occasionally i'll have to move everything to the right and ruin the whole game. then by the time i get to like 128-256-512-1024 down the left side, i'll end up with a 128 next to the 1024 and unable to move it to the top then i get screwed and lose.
