Level 290 is the fifteenth and last level level in Candy Clouds and the one hundred twenty-third jelly level. To pass this level, you must clear 43 double jelly squares and score at least 35,000 points in 50 moves or fewer. If you have extra moves left in this level, Sugar Crush will activate jelly fish to eat candies and score you additional points.
Typical of an episode finale around this point in the game, this level is very difficult. This is due to the sheer number of blockers. 43 double jelly squares hide behind meringues of up to the full five layers. meaning jelly fish do not help much. It is extremely difficult to make it through all the blockers within the 50 moves, even with only five colours.
The jellies at the bottom are next to impossible to reach due to the shape of the board and the fact they are behind five layer meringues. An incredibly lucky board is needed to beat this level, and you need consistent special candies and cascades all the way through to win, which is incredibly hard seeing due to the layout of the blockers. One will generally have a slow start with each attempt.
Do not pay much attention to the jelly fish, as they're not very useful. Do not mix them with any special candies either, as they'll most likely eat up meringue and waste your special candy. Just set them off when you can.
The level is pretty straightforward: Break as many meringues as fast as you can. Create vertical striped candies and blast them down. Make wrapped candies explode at the meringue. When you reach the bottom, create horizontal striped candies there.
Striped candy + wrapped candy and color bomb + striped candies are the most powerful combos in this level. Just make sure to set the wrapped candies off right above the meringue for impact.
The game will often create many cascades for you, usually 3-4 ones. Look out for color bomb matches as well, as you can be distracted with breaking the meringue.
