It's possible but unlikely this will happen naturally, but it depends on how good you are at the game - the longer you take to complete a level, the more likely you are to get this achievement. Since you'll probably need to focus specifically on the "Limits of possibility" and maybe even the "Chain reaction" achievements, when you go for those achievements in a game, if this achievement doesn't unlock, keep making matches until it does, then finish up the level.
