Puzzle Is Not a Game! Basic Structures of Challenge

Karhulahti's paper argues that puzzles, unlike strategic and kinesthetic challenges, cannot constitute games in the full sense, because they lack the dynamic, opponent-driven structure that prominent definitions of play and games treat as essential. The author proposes a tripartite framework of challenge structures, distinguishing puzzles (static, determinate), strategic challenges (dynamic, indeterminate), and kinesthetic challenges (bound to bodily execution), and uses this framework to classify familiar examples such as jigsaws, Yahtzee, chess, and strategy titles. The core thesis is that these three structures are the basic building blocks of videogame challenge, and that the static/dynamic divide is a structural property rather than a matter of player perception, as some critics have claimed.

The analysis rests on a distinction between solving a puzzle and executing its solution. Puzzles are treated as immaterial, intentional objects whose solutions can be determined independently of their material or semiotic form, drawing on Ingarden's literary ontology. Strategic and kinesthetic challenges, by contrast, are empirically bound processes. The paper illustrates how contemporary games combine these structures, citing titles such as Tetris, Machinarium, Zork, and Portal to show that puzzle, strategic, and kinesthetic elements frequently coexist within single works.

The paper's scope is conceptual and theoretical rather than empirical. It engages with the game studies literature on game definitions and challenge, and it addresses videogames broadly, with attention to genres such as turn-based strategy and classic adventure games. Its conclusions are that even genres built around one challenge type rarely achieve structural purity, and that the tripartite framework may plausibly extend to all games. The author leaves finer-grained substructural differences to future research.
