Make all your moves on one side only, as much as you possibly can. That way the ingredients will all fall down the same side and you’ll barely have to crush through any of the meringue wall to get them out of the exit.
In fact you can easily get through this level without the coconut wheels, too, if you just keep working on the candy on the one side, and keep your ingredients in line. If you get an easy shot at a wheel, use it to dent the meringue wall some more, but it isn’t necessary.
In Candy Crush Saga level 302 you need to bring the ingredients down to the bottom and score 40,000 points.
There are four ingredients to bring down in 50 moves, on a large board which makes level 302 seem easy. However there are five layered meringue blockers in the middle of the board and the corners to make it more difficult. The ingredients come from an ingredient maker and there are two of them either side of the centre column and then can only come off the board in the center five columns. There are two coconut wheels buried in marmalade and surrounded in blockers at the bottom corners of the board.
The main difficulty with this board is that you do not have enough moves to remove the centre blockers and get the ingredients down. You will therefore need to use special candies to remove them. Making wrapped and striped combinations is probably the best idea although, they will need to be in a useful place. Any striped candies could help and a color bomb and stripe combination could be great as well. You will find that vertical striped candies are the best at getting the ingredients down, once the blockers have been removed.
Boosters are not that useful on level 302, although starting with wrapped and striped candies or a color bomb might be useful. You can choose to start with a coconut wheel as well and these could knock out a good few blockers but only if it appears in a useful place.
