Level 1050 is the tenth level in Mellow Marshmallow and the 474th jelly level. To pass this level, you must clear 27 single and 8 double jelly squares in 37 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The jelly squares are positioned quite awkwardly. Some of them are totally isolated from the main board.
The board shape and blockers make it hard to reach the jelly squares.
The dark chocolate in most cases are hard to clear and reduce available board space, causing frequent shuffles that should happen. They also make it harder to create special candies to clear the isolated jellies.
The jellies are worth 62,000 points, which is more than the one-star target score.
In order to beat this level, you need to destroy a lot of jelly in hard-to-reach places and avoid the spread of copious chocolate.
At the start, some of the chocolate are isolated and the rest of the chocolate can be destroyed or isolated reasonably easily. Restricting/destroying the chocolate should be your initial target.
Unfortunately, there is so little room for manoeuvre on this board that you might struggle with that first task. Even if you manage to control the chocolate, there is very little space within which to make the specials and/or combinations that you need to beat this level.
Beyond that, you need some luck and good deployment of your basic skills: trying to make special candies, trying to achieve two things at once (e.g. jelly destruction and chocolate control) whenever possible, looking for cascades.
