Have bee stuck on Level 5413 for a couple of weeks (at least!). I do not know how to play this particular game, though I once—only once—came within a move of success…and that was possible ONLY with the use of multiple boosters. I have none now. All other efforts at Level 5413 have been fruitless and frustrating. I am now thoroughly bored with this game at this Level 5413. I do not know how to advance. SO, I QUIT!
