A secondary element is a board element of secondary function, and they are introduced later in the game (usually introduced officially on episode openers). They are not the primary idea of the game, and are not introduced in tutorial or beginner episodes, and they have many interesting properties to make gameplay more interesting. This term especially refers to such elements not considered as a blocker.
Much like blockers, non-blocker secondary elements can take one or more of the following functions:
- Transport candies from one place to another
- Spawning certain elements and blockers
- Moving candies
- Altering the nature of candies every turn
Like blockers, most of these elements individually take up one space. However, many of these elements have additional rules on the amount and where they can be located. Some, like teleporters, must occur in pairs to function properly, while others, such as the dispenser, must occur at an empty tile above a space to dispense items. Others almost always appear in groups, such as the conveyor belt. You should also note that most of these elements, unlike blockers, are permanent throughout the level.
These elements, like blockers, add to the challenge of the game by manipulating the nature of the board, the candies, and where new elements spawn.
