11 What Makes a Game “Fun”?

Let’s talk a little bit about this elusive concept of “fun.” Games, we are told, are supposed to be fun. The role of a game designer is, in most cases, to take a game and make it fun. Notice that we usually enclose the word “fun” in quotation marks, on purpose. The reasoning is that “fun” is not a particularly useful word for game designers. We instinctively know what it means, sure, but the word tells us nothing about how to create fun. What is fun? Where does it come from? What makes games fun in the first place?

Interesting decisions seem like they might be fun. Is that all there is to it? Not entirely, because it doesn’t say anything about why these kinds of decisions are fun. Or why uninteresting decisions are still fun for children. For this, we turn to Raph Koster and his book influential book Theory of Fun.

What a lot of Koster’s Theory of Fun boils down to is this: the fun of games comes from skill mastery. This is a pretty radical statement, because it equates “fun” with “learning”… and we often think “learning” is about “school” and many of us think school is about as not fun as you can get. So it deserves a little explanation.

Theory of Fun draws heavily on the work of psychologist Mihaly Csikszentmihalyi (pronounced just like it’s spelled, in case you’re wondering), who studied what he called the mental state of “flow” (we sometimes call it being “in the flow” or “in the zone”). This is a state of extreme focus of attention, where you tune out everything except the task you’re concentrating on, you become highly productive, and your brain gives you a shot of neurochemicals that is pleasurable – being in a flow state is literally a natural high.

Csikszentmihalyi identified three requirements for a flow state to exist:

  • You must be performing a challenging activity that requires skill.
  • The activity must provide clear goals and feedback.
  • The outcome is uncertain but can be influenced by your actions. (Csikszentmihalyi calls this the “paradox of control”: you are in control of your actions which gives you indirect control over the outcome, but you do not have direct control over the outcome.)

If you think about it, these requirements make sense. Why would your brain need to enter a flow state to begin with, blocking out all extraneous stimuli and hyper-focusing your attention on one activity? It would only do this if it needs to in order to succeed at the task. What conditions would there have to be for a flow state to make the difference between success and failure? See above – you’d need to be able to influence the activity through your skill towards a known goal.

Csikszentmihalyi also gave five effects of being in a flow state:

  • A merging of action and awareness: spontaneous, automatic action/reaction. In other words, you go on autopilot, doing things without thinking about them. (In fact, your brain is moving faster than the speed of thought – think of a time when you played a game like Tetris and got into a flow state, and then at some point it occurred to you that you were doing really well, and then you wondered how you could keep up with the blocks falling so fast, and as soon as you started to think about it the blocks were moving too fast and you lost. Or maybe that’s just me.)
  • Concentration on immediate tasks: complete focus, without any mind-wandering. You are not thinking about long-term tradeoffs or other tasks; your mind is in the here-and-now, because it has to be.
  • Loss of awareness of self, loss of ego. When you are in a flow state, you become one with your surroundings (in a Zen way, I suppose).
  • There is a distorted sense of time. Strangely, this can go both ways. In some cases, such as my Tetris example, time can seem to slow down and things seem to happen in slow motion. (Actually, what is happening is that your brain is acting so efficiently that it is working faster; everything else is still going at the same speed, but you are seeing things from your own point of reference.) Other times, time can seem to speed up; a common example is sitting down to play a game for “just five minutes”… and then six hours later, suddenly becoming aware that you burned away your whole evening.
  • The experience of the activity is an end in itself; it is done for its own sake and not for an external reward. Again, this feeds into the whole “here-and-now” thing, as you are not in a mental state where you can think that far ahead.

Flow States in Games

Simplifying this a bit, we know that to be in a flow state, an activity must be challenging. If it is too easy, then the brain has no reason to waste extraneous mental cycles, as a positive outcome is already assured. If it is too difficult, the brain still has no reason to try hard, because it knows it’s just going to fail anyway. The goal is to hit that sweet spot where the player can succeed… but only if they try hard. You’ll often see a graph that looks like this, to demonstrate:


All this says is that if you have a high skill level and are given an easy task, you’re bored; if you have a low skill level and are given a difficult task, you’re frustrated; but if the challenge level of an activity is comparable to your current skill level… flow state! And this is good for games, because this is where a lot of the fun of games comes from.

Note that “flow” and “fun” are not synonyms, although they are related. You can be in a flow state without playing a game (and in fact without having fun). For example, an office worker might get into a flow state while filling out a series of forms. They may be operating at the edge of their ability in filling out the forms as efficiently as possible, but there may not be any real learning going on, and the process may not be fun, merely meditative.

One Slight Problem

When you are faced with a challenging task, you get better at it. It’s fun because you are learning, remember? So, most people start out with an activity (like a game) with a low skill level, and if the game provides easy tasks, then so far so good. But what happens when the player gains some competency? If they keep getting the same easy tasks, the game becomes boring. This is essentially what happens in Tic-Tac-Toe when a child makes the transition to understanding the strategy of the game.

By the way, we can now answer our earlier question: why can children’s games get away with a lack of meaningful decision-making? The answer is that young children are still learning valuable skills from these games: how to roll a die, move a token on a board, spin a spinner, take turns, read and follow rules, determine when the game ends and who wins, and so on. These skills are not instinctive and must be taught and learned through repeated play. When the child masters these skills, that is about the time when decision-less games stop holding any lasting appeal.

Ideally, as a game designer, you would like your game to have slightly more lasting playability than Tic-Tac-Toe. What can you do? Games offer a number of solutions. Among them:

  • Increasing difficulty as the game progresses (we sometimes call this the “pacing” of a game). As the player gets better, they get access to more difficult levels or areas in a game. This is common with level-based video games.
  • Difficulty levels or handicaps, where better players can choose to face more difficult challenges.
  • Dynamic difficulty adjustment (“DDA”), a special kind of negative feedback loop where the game adjusts its difficulty during play based on the performance of the player.
  • Human opponents as opposition. Sure, you can get better at the game… but if your opponent is also getting better, the game can still remain challenging if it has sufficient depth. (This can fail if the skill levels of different players fall out of synch with one another. I like to play games with my wife, and we usually both start out at about the same skill level with any new game that really fascinates us both… but then sometimes, one of us will play the game a lot and become so much better than the other, that the game is effectively ruined for us. It is no longer a challenge.)
  • Player-created expert challenges, such as new levels made by players using level-creation tools.
  • Multiple layers of understanding (the whole “minute to learn, lifetime to master” thing that so many strategy games strive for). You can learn Chess in minutes, as there are only six different pieces… but then once you master that, you start to learn about which pieces are the most powerful and useful in different situations, and then you start to see the relationship between pieces, time, and area control, and then you can study book openings and famous games, and so on down the rabbit hole.
  • Jenova Chen’s flOw provides a novel solution to this: allow the player to change the difficulty level while playing based on their actions. Are you bored? Dive down a few levels and the action will pick up pretty fast. Are you overwhelmed? Run back to the earlier, easier levels (or the game will kick you back on its own if needed).
