Level 621 is the first level in Taffy Tropics and the 278th jelly level. To pass this level, you must clear 18 single and 18 double jelly squares in 18 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
The presence of three colours makes it easy to create special candies and is essential as special candies must be used to refill the candy frog which in turn is used to clear the jellies.
The jellies are worth 18,000 points. Hence, an additional 132,000 points for two stars and an additional 232,000 points for three stars have to be earned through matching of candies.
The jellies can only be cleared by using the candy frog which is and will be isolated when used to clear the jellies. Moreover, none of the rows and columns where the jellies are have candies. Hence, cascades that score a great many points are impossible.
With respect to the two and three star target scores, 10 moves and three candy colours, it is much better if cascades which may detonate special candies especially colour bombs are created than relying on sugar crush to meet those target scores.
With only 10 moves available, sugar crush is almost worthless with respect to the two and three star target scores. Hence, try to create as many special candies and cascades as possible as they are worth many more points.
This is the fourth level with only three colours in the whole game, the other early levels are levels 26, 31, 376, 587, 1020, and 1108. However, this is the first one which has such a wide and high candy area (5×7), resulting in plenty of cascades.
This level spawned sugar drops before this element was removed.
