The different level types bring different "Sugar Crush" effects at the end.
Moves - there is no real "Sugar Crush" effect here, except unactivated special candies being activated.
Jelly - for every move remaining, three jelly fish come on the screen and start eating the candies at random, giving you more points.
Ingredients/Candy Order - 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.
The Dreamworld is a new world separate from the main game that contains levels 1 to 665. They are exact replicas of the original levels except with more blocker introduced earlier and are more common on the board.
Level 350 is the most hated level of all time. Since it has been nerfed, its title is gone.
Timed levels are the only levels in which you are not pressured by the amount of moves you have left. However, you have to make quick decisions to earn three stars. Level 297 is the hardest timed level to earn three stars.
The first Candy Crush Saga support site, CrushingCandies.com, passed the limit of 5000 unique visitors per day in only 3 days.
The episode with most Candy Order levels in Reality is Wafer Wharf with 10. In Dreamworld, it is Sparkle Submarino with 11.
Level 295 and 327 have exactly the same layout with the only difference being the number of jellies. This has happened two other times in the 600s, but each has resulted in the higher level of the pair being replaced with a different type. Before this, no levels had been redesigned to a different type.
Level 65 became so famous once that several other levels based on level 65 are created, including 320 and 430.
Pre-nerf level 350, 440, and 530 are excruciating Jelly levels that are world finales.
All the level numbers ending in 65 except 665 are hard or very hard. Level 65 used to be the most hated level ever, level 165 used to be a very hard candy order level, level 265 is a hard jelly level, level 365 is a very hard candy order level, level 465 is a hard ingredients level, level 565 is a very hard jelly level, and level 765 is a very hard jelly level. However, this trend is broken when level 865 was released.
Levels in the iOS version are marked by a bubble looking element. Once the bubbles were opaque, but after the Meringue Moor update in late January, the bubbles became translucent and more colorful.
Levels ending in 47 (x47) are usually quite hard. Level 147 is an insanely hard jelly level. Level 347 is, once again, an insanely hard candy order level with a high amount of orders. Level 447 is a hard jelly level where mystery candies can be quite troublesome. Level 547 is a very hard jelly level due to the awkward layout. Level 647 is a hard candy order level with a complex order. Level 747 used to be an insanely hard jelly level due to six colors, chocolate spawners, liquorice swirls, and gaps in the board. Level 847 is a somewhat hard level due to the board layout and six colors.
Levels 83, 183 and 483 are jelly levels, Levels 283 and 683 are timed Levels, 383 is an ingredients level. Levels 583, 783 and 883 are candy order levels, 983 is a moves level. Hence, all levels that end in 83 have all five level types in the game.
Level 97 is a moves level. Levels 197, 597, 697, 797, and 997 are jelly, 897 is ingredients, 297 is a timed level, 397 and 497 are candy order. Therefore, all levels that end in 97 have all five level types in the game, too.
Levels that end in 99 trend to be hard difficulty or higher. However, there are some exception of them. Level 99 is somewhat hard, 199 is very hard, 399 is hard, 499 is again hard, 599 is somewhat hard, 699 is very hard, and it ends at 999 which is hard.
