A free, open-source site for finding and playing incremental games. Developers list their own games, and Galaxy plays each one in an iframe from the developer's URL; it does not store the game files itself.
Good for: Built specifically for incrementals. Lots of community features. Free cloud-save and OAuth APIs for developers. No forced ads or trackers.
Watch out for: Labelled beta. Only lists games that run in a browser. Whether a game stays playable depends on the developer's own hosting. Little coverage of Steam or mobile games.
Run by yhvr. The About page says 'no forced ads, no trackers, no paywalls, and it never will'. Source is MIT-licensed at gitlab.com/yhvr/galaxy-astro. Funded by Patreon.

A curated database of incremental games across web, mobile and Steam. Each entry has metadata tags (platform, monetization, playstyle, features) and links to where the game can be played.
Good for: Structured metadata such as monetization ('Free, Ads'), playstyle and features, with filters for New, Hot, Updated, Best new and On Sale. Covers every platform. Active review community.
Watch out for: Some metadata is incomplete (for example, Clickpocalypse II shows no developer or release date). It links out rather than hosting, so it depends on external pages staying up.
Supported via Patreon (patreon.com/dwightee). No third-party ad scripts were seen in the homepage HTML.

General indie game marketplace. The Incremental tag lists browser-playable and downloadable games.
Good for: Very large catalog (6,839 results on the tag page). Many games play in the browser. Developers upload their own files. Open revenue sharing.
Watch out for: Not specific to incrementals, and anyone can apply the tag, so quality varies a lot. Discovery relies on tags and sorting.
itch.io's creator FAQ says 'Advertisements will never be placed on any of your pages'.

Long-running browser game portal (launched 2006) and a historic home of Flash-era incremental games.
Good for: Huge back catalog, including many original homes of classic idle games (Anti-Idle, Realm Grinder, Clicker Heroes, Idle Wizard). Flash titles are served through the Ruffle emulator.
Watch out for: Some old games no longer work, and some pages are just shells: AdVenture Capitalist's URL now redirects to the homepage. Ruffle compatibility varies by game.
Announced on July 1, 2020 that it would stop accepting new games (Engadget, Wikipedia). Kongregate announced it was using Ruffle to bring Flash games back. Sold to Monumental in 2024 (Wikipedia). Whether it accepts new submissions now was not verified.

Large general browser-game portal (based in Leuven, Belgium) with Idle and Clicker tags.
Good for: Games play instantly on desktop and mobile. It hosts the official web relaunch of Clicker Heroes. Per-game pages show developer, engine and platform info.
Watch out for: General portal, not incremental-focused. Ads are integrated through the platform SDK. Tag pages are SEO-oriented.
Developer docs say monetization is 'video ads, banners, in-game purchases' with a revenue share after Full Launch. The page config references an ad-free subscription experiment. Tag counts on the Clicker Heroes page: Idle 506, Clicker 376.

Long-running browser game portal and publisher, with an Idle category of about 146 pages.
Good for: Classic Flash-era catalog. Flash games run through Ruffle, and some titles have native HTML builds (Clicker Heroes).
Watch out for: Several classic idle games are marked 'currently not available' because Ruffle can't run them, including Realm Grinder, Crusaders of the Lost Idols and Hero Simulator: Idle Adventures.
Game pages say 'We are using Ruffle to emulate Flash content, but it doesn't currently work for all games.' Ads are served by Playwire. It has a developer portal for submissions.

Valve's PC game store. The 'Idler' user tag (and the separate 'Incremental' tag) group idle games.
Good for: Largest catalog of downloadable and premium idle games (6,777 games tagged Idler, 8,279 tagged Incremental). Official ports of many Flash-era games live here.
Watch out for: Download client required, with no browser play. Tags are user-applied, so they are loose. Free-to-play titles often include in-app purchases.
Counts come from the Steam search API (category 'games'). No third-party ad scripts were seen in the tag page HTML.

Reddit community for incremental games. It keeps a community wiki that includes a list of incremental games.
Reddit blocked every fetch attempt (WebFetch, curl, browser), so nothing about the subreddit or its wiki was checked directly. The wiki list URL (reddit.com/r/incremental_games/wiki/list_of_incremental_games) is referenced by the Incremental Games fandom wiki. Galaxy's About page thanks r/incremental_games.

Fandom wiki about the incremental genre. Its main content is a community table of games (List:Games) with platforms and links.
Good for: Simple alphabetical list that links to games, developer sites and per-game wikis, and cross-links other directories.
Watch out for: Small and not very active (30 articles, 347 pages). Some entries are stale; Anti-Idle is marked 'Does not work as of 3/14/23'. Fandom ad placements.
The page links to the Reddit wiki list, the Steam Incremental tag and IncrementalDB as other lists. Stats come from the MediaWiki siteinfo API. Fandom ad slots (top_leaderboard) were present on List:Games.

Community-curated directory for finding and recommending incremental and idle games, made by dSolver.
Watch out for: Currently unreachable: both the homepage and /list-games returned HTTP 502 Bad Gateway on repeated attempts (2026-09-29). The public repo was last pushed in July 2020.
The games_plaza repo README says it 'makes it easy for people to find and recommend incremental/idle games'; the repo is MIT-licensed. A companion plaza-app repo (2022) is 'A desktop app optimized for people to play web-based incremental game'.

Mobile game review and discovery site (Android/iOS). The Incremental category showed 180 results.
Good for: Mobile-focused coverage with written reviews, price and IAP labels, and spec filters (offline, singleplayer, orientation).
Watch out for: Mobile only; no browser or Steam games. Display ads on game pages. The site renders with JavaScript, so it is hard to crawl.
Game pages link out to Google Play and the App Store with prices.

Directory of incremental and idle games that bills itself as 'The Home of Incremental Gaming'.
Good for: Incremental-specific, with platform filters including a large Flash section (164 Flash games), so it is useful for Flash-era discovery.
Watch out for: Many Flash-era links point to original portals where the games may no longer run.
The homepage says '648 Games and Counting!'. Google AdSense code is present.

Directory of incremental, idle and clicker games across browser, Steam, mobile and Roblox. It adds curated lists and guides and tracks which content creators cover each game.
Good for: Covers every platform, with category and platform filters and regularly dated guides.
Watch out for: Appears small or young: top entries have single-digit upvotes. Shows ads and promotes its own game.
Google AdSense code is present. The homepage lists 22 creators.

IncrementalGames.org (this site)
A directory that links out to where each game lives, with 28,349 games across browser, Steam and mobile. Games are tagged for ending, length, idle vs active pace, offline progress and update status, with live Steam, galaxy.click and GitHub signals.
Good for: deciding what to play next and finding games like one you loved.
Watch out for: no hosting, chat or forums; for community, galaxy.click and r/incremental_games are the places to be. Some tags come from developers' own descriptions rather than hands-on play, and each page says which.
