Level 1143 is the thirteenth level in Teapot Tower and the 533rd jelly level. To pass this level, you must clear 1 double jelly square in 30 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
This is a very interesting level. It is tricky, because there is a lot to do in 30 moves. It probably has many possible solutions and this author can only surmise that the approach suggested here is the easiest of them.
You only need to destroy one double jelly; the problem is its location, inside a chest protected by five keys, so you need to break the problem into components.
The first task is to get reasonable access to the keys and to the chest. In order to do that, you probably should target one (but not both) of the cake bombs. If you are able to clear a cake bomb within the first ten to fifteen moves, you are well on your way to closing out this level.
Once you have exploded one cake bomb, you should have plenty of space to make specials and finish the job.
This level might well take you a few goes however good you are, unless you resort to the "booster idea below".
