Crunching Candy Crush Saga

Every day, millions of people are playing Candy Crush, the latest mobile gaming craze that has garnered media attention and is even advertising on TV. I think there are several important lessons that can be learned from this game that can have an overall positive impact on the qulaity of mobile games being created today. How has this game captured so many players so quickly? A deconstruction of the game reveals that it has rcok solid underpinnings in three key areas: Core Mechanics, User Experience and Social Mechanics.


Core Game Mechanics

First, the game play mechanics have to be solid. No matter how beautifully polished and inviting a game, the core elements have to be engaging.

• The core mechanic of swapping candies to match 3 in a row is staggeringly simple. And while this mechanic is not new, the addition of more complex variations (such as 4 in a row, 5 in a row, and other formations to create special exploding candies that help the player) that affords the player a greater range of abilities  to change the outcome of the puzzles. Without a range of options, the game would quickly become stale. 
• Some candies obstruct and therefore represent antagonists. As the game progresses, more enemy candies are introduced that obstruct the player that creates a greater range of challenges. The spatial arrangement of the game board supports the effectiveness of these enemy candies and allows for challenges in which the enemy candies are either very strong, or even relatively weak, which bolsters player confidence.
• The difficulty of the game is very well done. Difficulty ramps up toward the end of stages and lowers at the beginning of stages. This gives players a sense of accomplishment in the early part of the stage and encourages players to remain engaged in completing stages.
• The game does an excellent job of allowing the player to prepare for challenges, by offering simple, clear instructions and opportunities to select paid power ups that will improve the odds of beating a level. The levels are puzzles to be solved. Successfully connecting patterns of three candies without consideration of the resulting formation will ensure failure. The ability to change the outcome of game play through thoughtful planning is a key to successful game design.
• The cost of failure is not so great as to push players away from the game. While lives can be lost to the point where further progression is prohibited, these lives regenerate over time and are constantly awarded for social interaction. There is therefore a low barrier to re-enter the game and keep players engaged.

User Experience
Candy crush achieves a high level of user experience both from an artistic as well as psychological point of view.

• The choice of candy as a key element in the game is deeply embedding in our childhood memories and evokes strong psychological associates with pleasure, adventure and happiness. "Candy Crush" is a wonderful choice for a name, having both a satisfying alliteration that rolls off the tongue and evokes a satisfying sense of mischief. The double meaning of "crush" also works nicely.
• The missions to complete stages in Candy Crush are all centered around helping likeable characters in distress. An example of this is the challenges of completing all 15 levels in the Minty Meadows stage to help a unicorn regain her lost horn. At first she is in tears, but after beating all the levels, she is overjoyed at her new replacement horn made of candy. In Achieving good deeds provokes strong sense of achievement and emotional connection to the characters in the game.
• The game has achieved a high level of artistic quality that underscores and enhances the user experience. The choice of vintage circus visual elements evokes an age of better days. The two mascots, a young girl and a tall Willy Wonka-esque figure of a man suggests an age of innocence, fantasy and wonder. The background music, with it's bells, harps and sleepy Edwardian overtones, supports this narrative of a dreamlike, turn of the century age of wonder. All of the buttons in the game have subtle squash and stretch animations that evoke a jelly candy like quality. The game play pieces are (of course) all made of candy that are rendered with a beautiful glossy finish that gives them a tactile and inviting look. The visual effects of candy being crushed sparkle like magic. All of these elements work in concert to further support a magical, world-of-candy narrative.

Social Mechanics
The most vital component here is the mechanism that encourages exchanges of information between friends. There are several elements that contribute to this:

• Multiple synced platforms: At first glance the benefit of multiple platforms that sync progress seems to be that it removes a barrier to play.
  
• Asynchronous lives: The real genius is that the game offers additional lives when playing on different platforms. King could easily have synchronized this as well, but extra lives were intentionally allowed. Player immediately recognize the opportunity to "cheat the system" and this mechanic encourages additional log-ins, which raises retention.
• Reliance upon Friends: Candy crush doesn't just allow you to see your friends, it creates an economy that creates dependence upon your friends in order to progress.
• Competition with friends: You are at the same time dependent upon your friends and competing with them at the same time. This fact is constantly reinforced every time you glance at the level progression map where you can clearly see which friends are ahead of you and which ones are behind you. This is further reinforced every time you beat a level. Candy Crush informs you of any friends you have beaten.

Candy Crush has one final vital key to success which is perhaps the most vital lesson to be learned; the designers have worked diligently to ensure the game can be won through skill and persistence, as evidenced by the players currently on the last level, 70% of whom have paid nothing. This is not only a feat of good design, it is also a feat of overall attention to creating a game that creates an incentive to progress based on desire rather than pain. Many games makes this mistake, notably those that feature ads and frequent pop-ups as a mechanism to anger or frustrate users into purchasing a paid version of the game. But these mechanics undermine the appeal of the game and in the long run, will drive users toward seeking other games that are free of these annoyances.

I think the overall quality of mobile games could improve from learning this key lesson, which is at the heart of my crush on Candy Crush.
