Use categories as promises
Puzzle, idle, runner, merge, arcade, simulation, and word game labels should describe what players actually do. A category that chases traffic but misleads players weakens the whole catalog.
Keep hybrid games honest
Many casual games mix loops. A merge game might include decoration, a runner might include upgrades, and an idle game might include collection. APKOF should lead with the dominant loop.
Separate theme from mechanics
A cooking theme does not always mean a cooking game. A city skin does not always mean simulation. Categories should describe gameplay first, theme second.
Make scanning easier
Good category labels let players skip what they do not want and find what fits their moment: five-minute puzzle, one-hand runner, calm merge, or low-pressure idle game.
APKOF categories should be useful to a player, not just attractive to a search engine.
