Idle & clicker

Idle and clicker games make progression itself the subject. You start with one action that produces a small amount of something, you spend that something on a way to produce more of it without acting, and from then on the game is about the shape of the growth rather than the actions producing it. Cookie Clicker gave the form its name; the design space turned out to be much larger than the joke it started as.

How incremental games are built

The structure is consistent. An early manual phase teaches the resource. Automation removes the manual work. Multipliers stack until the numbers stop being meaningful as quantities and start being meaningful as milestones. Then a prestige or reset mechanic trades all of it for a permanent bonus, and you do it again faster, with a new mechanic unlocked partway through.

Done badly this is a treadmill. Done well it is a genre about discovery: each reset reveals another layer of system you did not know was there, and the interesting decision is always when to reset rather than how fast to click. The best examples in this category are closer to puzzle games about optimisation than to time-wasters.

Where idle games live

These games are designed around absence, which makes them unusually flexible about platform. Mobile suits them because the game continues while the phone is in a pocket. Browsers suit them because a tab can be left open across a working day. Desktop releases suit the deeper ones, where late-game layers get complex enough to want a real screen and several panels at once. Some ship on console too, where they function as something to leave running.

The practical things to check are whether progress continues while the game is closed, whether saves sync across devices, and how the game handles being left for a week. Each listing states the platforms and links to where you can play or buy it.

Playing them well

The common mistake is treating an idle game as something to be actively played. Almost all of them are tuned so that checking in a few times a day outperforms watching the numbers rise, and almost all of them reach a point where the correct move is to close the game and come back later. Resetting earlier than feels comfortable is usually right too — the first prestige is nearly always taken too late.
