Level 1287 is the seventh level in Butter Rum Reef and the 614th jelly level.
To pass this level, you must clear 4 single and 17 double jelly squares in 40 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The fact is, you can totally ignore the popcorn and simply focus on destroying all cake bombs. Since the left cake has only single jellies below, breaking it after the other two cake bombs will result in instant win.
However, this still means that you need special candies to reach the bottom parts of the cake bomb and the isolated left cake bomb.
Horizontal striped candies are much easier to make at the bottom of the board instead of the top.
