Especilly when you are balancing stuff, lmao, the time it has to be standing for makes it some much easier, 10 seconds isn't that long so you can have a loosly balanced tower and still make it even if it's total crap. Of course, you still need to keep it up in a very loose way.

Not that I play this game for fun, I don't like it throwing adverts at me :(

Also I'm too lazy to link to it.
