Level

Candy Crush Saga currently has 290 levels, all within 20 episodes. Every episode has 15 levels except for the first two, which only have 10.

Level Types
In Candy Crush Saga, there are 5 different types of level: Jelly levels are the most frequent, making up 42% of the levels, whereas target score levels are the rarest, despite the first 5 levels all being target score levels.
 * Target score - get a certain amount of points in a certain amount of moves.
 * Jelly - clear all the jelly on the board.
 * Ingredients - bring all the ingredients down to the bottom of the board.
 * Timed - get a certain amount of points within the time limit.
 * Objectives - do all of the objectives within a certain amount of moves.

Sugar crush
The different level types bring different 'sugar crush' effects at the end.
 * Target score - there is no real sugar crush effect here, except unactivated special candies being activated.
 * Jelly - for every move remaining, three candy fish come on the screen and start eating the candies at random, giving you more points.
 * Ingredients + Objectives - both levels have the same effect. For every move remaining, a candy at random will become a striped candy, giving an extra 3000 points for every striped candy. Then they all activate.
 * Timed - any +5 candies left on the screen will turn into the exploding wrapped candy and activate itself.

Trivia

 * Many people consider jelly levels the hardest level type.
 * The 100th jelly level was level 235.
 * Level 65 is the most hated level of all time.
 * Timed levels are the only levels where you aren't pressured by the amount of moves you have left.
