Your first priority is to get rid of the chocolate before it spreads too far. It’s on a hard to reach part of the board and it can really hinder your game if you don’t get it under control quickly.
If you get synched up chameleon candies in the corner squares, you can use the marmalade coated colour bomb to take one layer of jelly off each at the same time. Other ways to reach those isolated jellies are wrapped and striped candy combos down the bottom, or a horizontal striped on the bottom row but it’s not easy by any standard.
In Candy Crush Saga level 449 you need to clear the jelly and score 60,000 points.
Most of the squares with jelly have candies on top of them that are locked in licorice cages. However there is a square in each corner that is not attached to the board that contains a rainbow candy with a double layer of jelly beneath it. There is also chocolate at the bottom of the board.
You will need to try to make special candies on level 449 that you can use to remove the jelly from the bottom corner squares. To do this you will need horizontal or vertical striped candies wrapped and striped combinations or color bombs. To have the room to make these you will need to unlock the candies on the main board. It is therefore wise, to do this to start with, unless you can make any special candies. However, there is chocolate at the bottom of the board so if you can remove this to start with, it will be helpful. It is impossible to get rid of it on the first move because of the positions of the blockers, but try to remove it if you can. However, do not get distracted by just fighting back the chocolate as the aim of the board is to clear the jelly not the chocolate and it may be possible to clear the jelly without removing the chocolate.
This board is a difficult one because of the reliance on getting the right special candies to remove the jellies in the bottom corners. It could be useful to start with a booster of a color bomb or stripe and wrapped candy to get you going with it. Jelly fish could be handy if they eat the right jelly, but often they do not. The sweet tooth and lollipop hammer may be useful during game play on level 449 as well.
