I have tried different types of boosters and everything else in between, but, my version of level 715 is seemingly not solveable. Also, I've combed the internet searching for a video of someone else playing it, only to find that everyone else's level 715 was my level 714!!! So, I looked for others' level 716 & 714, etc...thinking maybe it was a glitch, but can't find it ANYWHERE!! PLEASE HELP!! I've come so far, but, now I'm close to giving up entirely.
