As you might have guessed, intrinsic and extrinsic motivation is all about motivation. It tries to classify our reasons for being motivated to do something and explains why we are motivated. Much research has been done into motivation and quite some theories have been proposed to explain motivation, extrinsic and intrinsic motivation is just one of those.

Actually, I already wrote an article on another theory in motivation called: ‘wanting vs liking’. Here is a link if you haven’t read it already: The striking difference between liking and wanting. Back to intrinsic and extrinsic motivation and what these actually are. Any reason that explains our motivation to do something can be classified as an intrinsic motivator or an extrinsic motivator. When you are intrinsically motivated it means that you do something simply because you enjoy doing it. In other words, we think it is fun to do (Schmitt & Lahroodi, 2008). Extrinsic motivation, on the other hand, is when you are being motivated to do something because of an incentive. The incentive can be a reward but also a punishment, anything that motivates us as long as it doesn’t come from within our self. So intrinsic motivation is when you like drawing simply because you enjoy drawing. But when you draw for art class in order to can get a good grade, it is extrinsic motivation. The grade is the incentive. What intrinsically motivates you is very personal, it is different for everyone. What you find extrinsically motivating is personal as well but also relies on something called incentive salience: how noticeable is the incentive? (Berridge, 2007). Emotion has a role in this as well: associating an incentive with a specific emotion can make the incentive be more salient and motivating (Robinson & Berridge, 2001).

It is important to keep intrinsic and extrinsic motivation in mind when you design you game. It can have an effect on your player’s behavior and how they like the game. Relying on extrinsic motivation too much can kill creativity and problem solving. According to Glucksberg (1962) people can become distracted by (monetary) rewards when they are offered one. This distraction inhabits people to solve a problem which requires creative thinking. Extrinsic motivation can also kill motivation. Especially rewards can undermine the intrinsic motivation people have for an activity (Deci, 1999). People will enjoy the activity less and won’t do it as often anymore. As we know from my previous article, people can ‘want’ to do something without actually liking the activity any more. So how can you know that players are playing your game because they ‘like’ it from looking at your game’s analytics? How can you know whether your players are just mindlessly playing your game because they became addicted to it? Sure, if your goal is to just generate money and you don’t care whether or not your players acutely like playing your game, go ahead, it can be a conscious choice. But if you want your players to look forward to your game and actually liking to play it, consider relying more on your player’s intrinsic motivation.

Intrinsically motivative games are games without any form of reward or punishment. We often regard these kinds of games as ‘just play’. Most forms of play are intrinsic motivation: it is a voluntarily action, there is no pressure and there are no rewards or punishment for participating or not. Some other good intrinsic motivators are exploration and curiosity. Examples of games that (mostly) rely on intrinsic motivation are games such as the Stanley parable, flow, minecraft and flower. None of these games have scores and you can’t loose or win, there are no incentives.

Games that rely on external motivation are games you play solely for the rewards. Gamification is a good example: it tries to make every day, boring tasks fun by rewarding the player. Duolingo uses gamification to make learning a new language more fun and gamy (though you might start learning a language because you’d like to learn the language, which is an intrinsic motivator). Most games, however, are a mix of extrinsic and intrinsic motivators. Some games might rely more on intrinsic motivators while others rely more on extrinsic motivators. You probably start playing a game out of curiosity, an intrinsic motivator. While failing a level or dying, for example, often is an extrinsic motivator. Especially if it makes you want to try again.

Some ideas for your own games
Extrinsic motivators aren’t all bad, they are naturally present in games. Think of any form of punishment such as failing a level, losing a live or losing a battle. But also reward such as a score or stars you get for finishing a level. Time is also often used in games as an external motivator to pressure players. Think about solving a puzzle within a certain time. Another extrinsic motivator is competition, especially because it is rewarding for the player(s) who won. It can also motivate the others to try harder next time. There are also extrinsic motivators that are less part of a game like daily rewards you get if you login to the game every day or notifications to remind you that you haven’t played yet today. When designing more for intrinsic motivators keep this quote in mind: “The reward is the activity itself” (Ryan & Deci, 2002). People will play your game because they enjoy playing your game, it is that simple. Rely more on the natural curiosity people have. What if you design a match-3 game with power-up? You can choose to create guided tutorials and explain players how to create and use them. But what if you choose to leave those tutorials out and leave it up to the player to discover what is possible? Ask yourself if someone can play the game without understanding this mechanic or feature. In that case, maybe you should leave it to the player’s curiosity to discover the feature or mechanic. Of course you might consider a tutorial if your game is not playable before the player understands the mechanic or feature. You can also try to make your game “easy to play, hard to master”. Mastery is one of those intrinsic motivators that will make people play a game or level over and over. Consider adding an extrinsic motivator in the form on competition to create some social pressure.

I always find it important to ask questions during the design process. Some good questions to ask yourself if you are designing a mobile game where retention is important are:

Could it be they only play because they get a reward that is useful in your game? Maybe they don’t play your game because they like it anymore, but because of the rewards. Maybe you design a game that requires players to think creatively our to find a solution to the puzzle outside the box. It might not be a good idea to include too many rewards or punishments, player since people who are offered a reward become distracted by it and their creativity suffers (Glucksberg, 1962). Try to stay away from time limits, they can make it harder for players to come up with a solution.
