Level 1497 is the seventh level in Precious Pond and the 708th jelly level. To pass this level, you must clear 81 double jelly squares in 16 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
There is no difficulty in getting two and three stars as the two and three star target scores are only 20,000 points and 30,000 points respectively. The jellies are worth 162,000 points which is more than the two and three star score requirements.
