Idle game meaning, in one sentence
An idle game is a game that plays itself while you are away: production keeps running, and your job is to decide what to buy, upgrade or automate next. "Idle" means "doing nothing", and that is the joke of the genre: you progress even when you do nothing. They are also called idle clicker games, incremental games or simply idlers.
How idle games work
- You start by hand. You click, tap or collect something yourself: a cookie, a monster, a piece of trash.
- You buy producers. Buildings, workers or machines do the job for you, faster than you ever could.
- The game keeps going without you. Most idle games keep earning while you are away, so coming back is a reward.
- You choose what comes next. The real game is in the decisions: which upgrade, which producer, what to automate.
- You prestige. At some point you reset on purpose to earn a permanent bonus, and go much further on the next run.
Idle, incremental, clicker: the words players use
- Idle game: stresses progress while you are away.
- Incremental game: stresses numbers that keep growing and new systems that unlock. More in what incremental games are.
- Clicker game: starts with clicking before automation takes over.
- Prestige (or ascension, rebirth): a reset you choose, for a permanent bonus.
- Offline progress: what the game earns while it is closed.
- Number go up: how players sum up the pleasure of the genre.
