Idle Harbour

Idle and incremental games, reviewed slowly

A quiet harbour for games that keep counting while you are away

Idle games are the ones where numbers grow on their own. You set something in motion, step away, and come back to a bigger pile of cookies, paperclips or catnip. Idle Harbour reviews the ones that run in an ordinary web browser, checks each on its official site, and tells you plainly what it asks of your time and your wallet.

Moored here

Eight games, roughly in order from gentlest start to longest voyage. Each verdict is a short version of the full review.

Cookie Clicker

Best first idle game

The friendliest first step into idle games. Free in the browser with ads, endlessly deep if you want it, perfectly fine to treat as a background joke if you do not.

How a game earns a berth

We do not list every clicker on the internet. A game gets a place in the harbour only if it passes all five checks below, and we repeat the checks before any review is updated.

  1. It runs in a browser today. We open the official page ourselves. If it needs a download to start, or the page no longer loads, it does not get a review.
  2. Progress keeps moving. Something has to grow, build or accumulate without a constant stream of clicks. That is the whole point of the genre.
  3. The money side is described plainly. Free, ad-supported, donation-funded, a paid full version, optional purchases: we say which, using what the developer's own pages show.
  4. It lets you leave. Saves that stick, sensible pacing, no penalty for closing the tab for a week. A game that punishes you for having a life does not fit here.
  5. It has an official home. Every link goes to the developer's or publisher's own page. No mirrors, no re-uploads, no tracking codes.

The longer version of this lives on How we review.

Questions from the quay

What counts as an idle or incremental game here?

A game whose main loop is numbers that grow, often while you are not touching anything, and that keeps adding new layers as they grow. Some, like Cookie Clicker or Antimatter Dimensions, are pure versions of the idea. Others, like A Dark Room and Candy Box 2, start as incremental games and slowly turn into small adventures. Our glossary explains the usual vocabulary.

Do I need to install anything?

No. All eight games on this site start in a desktop web browser from their official page. Several also have separate Steam or mobile releases, which we mention in each review. One caution: the developer of Universal Paperclips says its web version was not designed for phones and points mobile players to the app instead.

Do these games cost money?

Every game here can be started in the browser without paying. How they are funded varies: Cookie Clicker's web page shows ads, Melvor Idle offers a free demo and a paid full version, Antimatter Dimensions has an optional shop that its own text calls unnecessary for progress, and several are simply free with an optional donation link. Each review spells out the details.

Where is my progress saved?

Unless you sign in to an account the game offers, progress usually lives in the browser you played in, so clearing site data can wipe it. Kittens Game and Trimps both have visible export options; copying a save somewhere safe now and then is a good habit.

Why are there no star ratings or scores?

Because a score hides the part that matters most with idle games: whether the rhythm suits you. Instead, every review ends with who the game fits, who might skip it, and a short list of fair winds and headwinds.

Is Idle Harbour connected to any of these games?

No. We are an independent editorial site. We are not paid by the studios, links carry no affiliate codes, and game names belong to their owners. See the disclaimer for the formal version.

What if a game starts taking over my evenings?

It happens to most players at some point. Our guide on keeping idle games idle has practical habits for that, from choosing finite games to letting offline progress do the work.
