Candy Crush Level 46 appears to be tough than it actually is. Just look for clearing the jelly. It becomes fairly easier as soon as you concentrate on eliminating the blocks to start with and forming candy sets with candies within the nets to break. After the center nets are eliminated, you are only left with eliminating the blocks and jelly left.
Remember to aim for candies that are surrounded with jellies at levels that need you to eliminate all the jellies. Targeting jellies that are close to jelly-filled candy is also useful. Doing it this way will help you to eliminate most of the jelly filled spaces in a couple of moves.
