very interesting variation, I like it. Didn't notice the instructions when I played so I didn't realize I could put 4s so my strategy mainly consisted of trying to figure out where the worst place to put a 2 would be especially at the end when it was filling up to get it to catch twos by itself or other singular numbers. Won in the end so I'm pretty content: http://i.imgur.com/7E3WBQk.png
pretty cool idea, though I don't think I could have passed just listening to the waves, without my music collection I don't think I'd be able to muster the patience for this, well. maybe.
