New things[]
Level 434 is unofficially the first mixed level with toffee swirl order, due to redesigning.
Rainbow Runaway is a medium episode, with a mean 3.87. It has one somewhat hard level: 438, one hard level: 440, and one extremely hard level: 430, and one nearly impossible level: 435. The rest of the episode is quite easy to complete. Therefore, it is much easier than the previous episode, Soda Swamp (Episode 29).
A website, crushingcandies.com, hoaxed a fake episode 30. It was supposedly called "Cupcake Forest" and contained 7 jelly levels, 5 ingredients levels, 2 candy order levels, and 1 timed level. Crushingcandies.com then explained they got the false information from the regular Candy Crush Saga Wikipedia page and apologised for the false information.
Upon its release in HTML5, the quit button was changed.
Before the release, if you scrolled to the very top of the board, the first three spaces of the episode could be seen, but the spaces had no level type icon or number, and the colour was dark blue, although this episode's colour is pink.
Upon its release, when you played a timed level, it displayed "Get (required points) points!". It was later changed to "Get (required points) points in (time) seconds!".
This episode used to start a trend in which all levels ending in 0 or a multiple of 10 are somewhat hard or higher, from level 440 until 570. Now, it continues this trend, with level 290 being the one to start this trend and level 560 to end it.
Even though this episode is based on rainbows, there were hardly any rainbow candies at all before they were removed from the game. Level 432 was redesigned to have chameleon candy cannons, however, fitting the episode's theme.
This is the second episode with a compound word, after Polkapalooza.
This is the first episode with a rainbow theme.
This is the last episode until Scrumptious Studio to not be reused or altered in any way. It is the only episode exempt from this trend that started in Polkapalooza. It was not until the dreaded April Fool's Day event when it ended.
