What category is Prune?

Apple's App Store has fifteen game categories. None of them fit Prune.

Open the App Store on your phone right now. Tap Games. Look at the category list.

Fifteen categories. Now try to place Prune.

Prune is the game where you grow a single tree toward light. You swipe to trim branches. Light streams in, or doesn't, and branches die. No score multiplier. No achievements. No enemies. No second tree. You tend one tree, you fail most of them, and occasionally you make something beautiful.

It sits in Puzzle because there's nowhere else to put it. But Prune is not a puzzle. A puzzle has a solution. Prune has a practice.

This isn't a complaint about Apple's UI. It's a diagnosis of what the App Store's taxonomy reveals about what the industry thinks games are for. According to the categories on offer, a game is something you win, solve, race, or role-play through. If you're not racing toward an objective, competing against other players, or working through a designed solution, you're not playing a game. You're doing something the taxonomy has no name for.

Four kinds of play, and the one we've erased

Roger Caillois, writing in 1961, gave us the most useful taxonomy of play anyone's produced. Four categories: agon (competition), alea (chance), mimicry (role-play), and ilinx (vertigo). But the more important axis in Caillois runs perpendicular to these four. On one end: ludus, structured play with explicit rules and goals. On the other end: paidia, free improvisational play with no score and no objective.

Contemporary mainstream games have collapsed the entire spectrum into one narrow band: agon plus ludus. Competition plus structure. Everything the industry ships, markets, and categorizes lives in that corner. The other three quadrants, and especially paidia without agon, have no home.

You can see this in what's missing from Apple's taxonomy. No category for building without winning. No category for tending. No category for the kind of play where you arrange stones on a beach knowing the tide will take them. The industry has a word for that mode: "cozy." Which is what marketing reaches for when the actual concept has no name.

"Cozy" is a vibe. Paidia is a mode. They're not the same thing. Most cozy games are still structured around progression, unlockables, and compulsion loops. They just use warmer colors.

The metric eats the meaning

The philosopher C. Thi Nguyen has a useful concept for what happens when structured games colonize unstructured activity. He calls it value capture. The simplified values inside a game (scores, streaks, rankings) start to replace the real-world values the activity was originally about. You started running because you liked being outside. Now you're running to keep your Strava ranking. The metric ate the meaning.

Gamification is value capture at industrial scale. Your language-learning app is a streak counter with vocabulary attached. Your meditation app has a consistency score. Your journaling app nudges you toward daily entries whether or not you have anything to say. Every piece of contemplative practice the tech industry has touched has been reduced to the same loop: score, streak, shame, subscribe.

D.W. Winnicott saw something like this coming in 1971. He argued that creative play isn't a luxury. It's how people feel real. He had a phrase about most people experiencing just enough creativity to recognize its absence, a sense of going through the motions while caught up in something external that wasn't theirs. He was writing before the personal computer. He'd have recognized the phone immediately.

What a refusal looks like

The games that belong in the missing category all refuse the same things.

Prune refuses the score. Journey refuses language and competition. Monument Valley refuses difficulty escalation. Townscaper refuses goals entirely. Tiny Glade refuses grids, timers, and win conditions. ABZU refuses danger. Viridi refuses urgency.

None of them look alike. They're made by different studios, in different engines, across a decade. They don't share an aesthetic. Some are beautiful, some are austere. What they share is structural: they all strip out the machinery that turns play into optimization. No leaderboards. No streaks. No purchase loops. No daily notifications reminding you that you haven't played today and your tree misses you.

The category they belong to isn't cozy, isn't zen, isn't mindful. It's the category that survives when you remove everything an engagement-optimized game is trying to do.

The missing word

The category still doesn't have a name. Contemplative games is the closest English gets, but the word reads as pious when the best games in this mode (Townscaper, Tiny Glade) are funny and freewheeling. Slow games undersells Journey. Zen games is a genre shelf in a bookstore. Quiet games describes the sound design, not the mode.

The taxonomy gap is a philosophical gap first, a marketing gap second, and a UI problem third. We don't have the vocabulary because the culture doesn't have the concept. And we don't have the concept because the tech industry has spent twenty years convincing us that play and optimization are the same activity with different paint.

There's a site that's been trying to collect these games in one place: contemplativegames.com. It's not a store. It's a curated list. Prune is there. So are Monument Valley, Journey, Townscaper, Tiny Glade, Viridi, ABZU. Games that don't belong together on any existing marketing taxonomy but belong together in the category that hasn't been named yet.

The App Store will add a new category eventually. They always do. By the time they get around to it, the games will already exist and the people who love them will already know what to call them. That's how every new category starts. Someone builds the thing before the taxonomy is ready.

Prune is a puzzle the way a walk is a commute.
