Fun is the sensation of a brain acquiring a pattern, so a game stops being fun when there is nothing left to learn.
Koster's 2004 argument accounts for why games become boring at the point of mastery, why difficulty must keep pace with skill, and why a solved game is dead. It explains a real pattern in play and generalises further than its evidence.
In practice
- A puzzle game loses its player the moment the trick is understood, whatever content remains.
- A task that is neither learnable nor familiar is not fun in either direction, which the account handles poorly.
- Possible explanations
- The explanation offered is learning: fun is the feeling of a brain acquiring a pattern, so interest lasts while patterns remain and ends at mastery.
- In its favour
- It accounts for why games become boring at mastery, why difficulty must track skill, and why a solved game is dead, which designers find operationally useful.
- Against it
- It is a designer's account rather than a tested theory, it does not explain forms of play with little to master, such as social or narrative play, and it treats learning as the only source of enjoyment.
- Standing
- A designer's account rather than a tested psychological theory; it does not explain forms of play with little to master, and it treats a family of pleasures as one.
