The Candy Crush Quiz

Although Bejeweled is the most successful Candy Crush "match three" predecessor, the Russian game Shariki (which means "the balls") was probably the first, circa the early 1990s.

Although you'll want to fill the empty hearts (along with freeing animals and octopuses, dunking cookies and spreading the jam), you actually don't want to capture hearts. Because THAT would be weird.

Users can ask friends for tickets and hearts, which help them advance. This also reminds people about the game, which keeps them playing.

By making matches closer to the bottom of the screen the board will change more, moving candies into different spots and bringing cookies closer to the bottom.

It's hard to make progress if you're being blocked on parts of the board, so target those people first to gain sweet freedom!

The game actually hands out merit-based prizes for finishing the level in the least moves possible, as well as for having remaining candies. Such bonus points could result in a promotion from one star to three!

Although his name sounds sweet, Bubblegum Troll likes to wreak all sorts of havoc, first encountering main character Tiffi when he steals her candy in Bubblegum Bridge.

Every user is playing the character of Tiffi, who gets really excited when her player passes a level and actually cries when failure occurs.

A user's rank is displayed under the avatar, which is surrounded by a frame. For every five levels passed the gamer is awarded a neat new frame, which shows of certain prowess.

Candy crush ranked as the third most popular app people logged into via Facebook for 2019. Only Spotify and Pinterest were more popular (Tinder was No. 4).
