Here we go again. BO-RING. Playing Level 1628 with Facebook interface on MacBookPro. Yep. Total times played: over 100. Total times failed: over 100. Total times achieved score of more than 50 percent of the required total of 60,000 points: about twice--but one of those two times, I missed it by only 480 points.
Playing with bonus candies has no effect.
There doesn't seem to be a specific problem to point to, except perhaps that only one move is usually available until well into the round. The level simply doesn't work.
And puh-leeze--don't bother with "tips." When only one move is available, you take it. If there happens to be a special candy--which there rarely is--you play it. If it is possible to play from the bottom, that's what you do.
Generally, however, the round is just a bust.
