It is one of the most hated blockers as it spreads every move if you do not "eat" it. It can also disrupt your moves. Chocolate can be eaten by breaking the candies adjacent to it, or through any special candy's effects reaching the chocolate.
There are two types of chocolate, brown chocolate and white chocolate. Brown chocolate (black chocolate or dark chocolate) is introduced in episode 4, Shortcake Shores, along with chocolate type levels. White chocolate is introduced in episode 10, Candycane Isle. The brown and white chocolate coexist in the same level starting from episode 15, Wafer Workshop.
The brown chocolate is similar to a chocolate in Candy Crush Saga.
In a level with both chocolate types, if you eat a brown chocolate during a move, the white chocolate will still multiply because it wasn't cleared. The same thing goes vice-versa.
If a chocolate is cleared:
On web, icon will break, heal again and counter is counted.
On mobile, counter only counts.
Unlike locked chocolate in Candy Crush Saga (that was introduced in Episode 72), you must remove liquorice lock by special candy. However, in Candy Crush Soda Saga, you can remove it by matching candies that do not need special candy.
In some devices, including web and mobile, the brown chocolate is darker than the brown one than other devices.
As of a recent update, the white chocolate icon is used if a level requires white chocolate.
