As most folks know by now, nearly a year ago, Candy Crush Saga Level 713 was altered (on all platforms) so that it no longer features bombs dropping from above. As a result, it makes winning the level easier in and of itself, which I presume was King's intent. However, since the bombs or no longer there, there is almost no chance for making combinations that would lead to the point totals that used to be accessible on the level. Therefore, achieving three stars is next to impossible (theoretically you could get the greatest cascade known to man, but for practical reasons, achieving three stars is effectively impossible). A King moderator has addressed the issue in the past: https://care.king.com/en/candy-crush-saga/level-713-1702663906 but said answer didn't seem to get that this isn't a case of people complaining about a difficult level. Difficult levels are fine. We all understand difficult levels. This, however, is a glitch caused by an alteration to a level that has the presumably unforeseen result of three stars being basically unreachable.
People might argue, "King wants you to pay for boosters, so that's why this level is so hard, so that you pay for boosters." I don't even necessarily have an issue had that been the case, but I don't believe that to be the case on this level, since adding boosters wouldn't even really help you here, since the point totals are so far out of reach (as the combinations don't exist to get there). I think this is just a simple mistake. But is King even aware that there is a mistake here? Their moderator's reply didn't seem to indicate that they get what the issue is here.
