Whenever I come to a level that seem impossible to pass, I check on Google, which usually sends me to YouTube for watching someone pass this level with or without boosters. I find that they have different, less difficult set ups than I do and often more moves! Why is that? I try on mobile devices and my pc. For example level 12859, my latest headache. This is the screen I find on you tube
and this is the one I get
Notice the difference in difficulty and moves?
