Level 1242 is the seventh level in Drizzly Dale and the 587th jelly level. To pass this level, you must clear 4 single and 13 double jelly squares in 38 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
There is no difficulty in earning two and three stars as the two and three star target scores are only 20,000 and 30,000 points respectively. The jellies are worth 30,000 points, which is more than the two star target score and equal to the three star target score.
