Platform: Steamworks · free once the $100 app fee is paid · at least two weeks before release
Valve requires a Coming Soon page to be live for at least two weeks before a new product releases, and its wishlist documentation is blunter: "Put up a Coming Soon page as soon as you're ready and able." Every wishlist collected before launch becomes an email or push notification to that player when the game releases.
In Zukowski's write-up, the solo developer of Void Miner had his Steam page live for six months before launch. Two weeks is the minimum, not the plan. You need a capsule image, screenshots, a short description and ideally a trailer; see our Steam page examples for how idle games handle each.
Watch out for: A rushed page with placeholder art converts visitors poorly and you only get one first impression from each. Make the capsule and first screenshot readable at thumbnail size before you announce.
02
Platform: Steamworks · wishlist notifications
Steam notifies wishlisters when the game releases, again if an Early Access game moves to full release, and when a discount meets three conditions: at least 20 percent off, on the lowest-priced package, lasting more than 8 hours. Each app has roughly a two-week email cooldown, and only users with verified email addresses get them.
So a wishlist is a stored notification. Launch is the biggest one, and your first qualifying discount is the second. Plan both deliberately rather than discounting by 10 percent and wondering why nobody heard.
Watch out for: Discounting only a deluxe edition while the base game stays full price does not trigger the emails. Discount the cheapest package.
03
Platform: Steam demo app · free · optional separate store page
A Steam demo is a separate app linked to your game. It can show as a button or a large green box on your main page, and can optionally have its own store page that links back to the full game. Valve notes that demos can appear anywhere a free game can, including trending lists and tag pages, and that demo saves can be stored to the full game's cloud storage so players continue where they left off.
That carry-over matters for incrementals more than most genres: a player who has spent two hours in the demo is buying the rest of their own save. Void Miner's demo launched soon after its page, in Zukowski's account.
Watch out for: Valve allows the demo's wishlist notification only once, within 14 days of the demo's first release, and recommends disabling achievements in demos and granting them in the full game.
04
Platform: Steam · free · February, June and October
Next Fest runs three times a year, in February, June and October. Valve's rules: the game must have a publicly playable demo by the time the fest begins, must not release before that edition ends, needs a public store page, and "titles may only participate in ONE Next Fest." Demo builds should go to review three weeks before, or five weeks if you want the demo live for the Press Preview that starts 11 days early.
Because you get one shot, enter the edition just before launch, with your best demo. Zukowski reports that Void Miner's last Next Fest before launch earned about 1,400 wishlists.
Watch out for: Next Fest rewards demos that hook fast. If your incremental's first ten minutes are slow, tighten them before the fest, not after.

Platform: Steam · paid
Valve runs themed fests alongside its seasonal sales, and several fit the genre. Its upcoming events page lists an Auto-Battler RPG Fest from November 16 to 23, 2026, a Desktop Companion Fest from January 14 to 18, 2027, described as "Games that sit on your desktop and keep you company while you do other things", and a Shop Keeper Fest from January 25 to February 1, 2027.
Rusty's Retirement is the model of a desktop idler: its store page calls it an idle farming simulator that sits at the bottom of your screen, and it had 97 percent positive Steam reviews in November 2026. Our catalog tags 60 desktop-companion games; if yours is one of them, the Desktop Companion Fest is built for it.
Watch out for: Each fest has its own eligibility criteria and registration link, and the deadlines come well before the fest. Check the upcoming events page monthly.
06
Platform: Steam · paid
Zukowski's case study is clear on what moved Void Miner: "Content creators & festivals got him the majority of wishlist spikes." The developer did early YouTuber outreach, and the YouTuber Idle Cub played it. The game launched with 8,449 wishlists and sold 10,000 copies in its first 12 days, according to the article.
Idle and incremental games have their own YouTube niche, as that example shows. Send a short email with a Steam key, a one-line hook, and a link to the demo.
Watch out for: Creators want games that are fun to watch in the first minutes. If your game is mostly menus, give them a save file or a mode that starts later in the progression.
07
Build the stream into the game: best for games people leave running while they stream or work
Platform: Steam · free
Some idle games market themselves by being on screen. Rusty's Retirement lists Twitch integration: viewers can build a farm together and control their robot with chat commands like !plant and !water. Bongo Cat, a free taskbar game where the cat punches your taskbar on each key press, is designed to sit visibly on a desktop while you type and play other games, and had about 30,000 Steam reviews in November 2026.
If your game can run beside something else, design for the screenshot or the stream overlay: a small, readable, charming strip that makes viewers ask what it is.
Watch out for: Chat integrations need moderation and rate limits, and an always-visible game is judged on CPU use. Test both before you pitch streamers.
08
Platform: r/incremental_games and other subreddits · free
Reddit is where the incremental community talks, but Zukowski reports it did not work well as a marketing channel for Void Miner: the developer was banned and had posts pulled a few times, and Reddit earned him roughly 100 wishlists in total. His recommendation is an intro announcement post, a demo launch post and a final launch post.
Post when you have something playable, link it directly, and stay in the comments. Our guide to where to post your incremental game covers the subreddit alongside other venues.
Watch out for: Repeated self-promotion gets removed. Read the subreddit's rules before each post and treat Reddit as a place for feedback first.
09
Platform: itch.io, galaxy.click, Armor Games · free
Many incrementals can run in a browser, and a web demo removes the download step entirely. Void Miner's developer uploaded a web demo to browser portals including Armor Games; Zukowski counted only about 30 wishlists from it, but suggests portals are useful for gathering feedback.
Treat the web demo as a playtest with a wishlist link at the end, not as a wishlist machine. If your audience is the incremental community, galaxy.click and itch.io are a better fit than general portals.
Watch out for: Do not let the web demo cover the whole game. Players who finish it in the browser have less reason to buy the Steam version.

Mushies!: best for a Coming Soon page paired with a free browser demo
Platform: Browser, Steam
Mushies! is the site maintainer's own cozy pixel-art mushroom-village clicker, so this is an example in progress, not a success story: it has no launch numbers yet. Its Steam page is up as Coming Soon (app 4279180) with 11 screenshots, a trailer and a short description that names the genre in its first sentence: "Create a thriving mushroom village in this cozy incremental adventure."
Its demo is a free HTML5 build on itch.io, exported from the same Godot project as the Steam version, so anyone can try it in a browser and go on to wishlist. That is the cheap version of the playbook above: page early, demo early, then festivals.
Watch out for: A browser demo on itch.io does not get Steam's demo features, such as save carry-over or appearing in Steam's free lists. A Steam demo is worth adding before Next Fest.
11
Platform: Steam Playtest · free · separate app with no store page
Steam Playtest is a free child app associated with your main game. Players sign up from a section on your store page, you choose how many get in, and Valve says it does not affect your reviews, wishlists or refunds. Valve suggests the most common use is before release, once a Coming Soon page is up.
For incrementals, a playtest is the best way to find the walls: where players stall, quit or prestige too early. Ask testers to send save exports so you can read their progress.
Watch out for: You cannot charge for a playtest; Valve says it is not OK to charge customers to access one. Keep it free and time-limited.

Platform: Steam · paid
Nodebuster, a short run-based incremental, sold for $2.99 on Steam in November 2026 and had 97 percent positive reviews out of about 14,000. Tower Wizard was also $2.99, and Rusty's Retirement $6.99. A low price turns a creator's clip into a purchase without much thought, which suits a genre bought on a whim.
Zukowski's Void Miner article makes the related point about conversion: a familiar genre with well-executed tropes means "Users are not taking a chance." Our monetization guide compares premium prices with free-to-play models.
Watch out for: At $2.99, Steam's cut and refunds leave little per sale, so a cheap game needs volume. Make sure the price matches the length; players review value as well as fun.

IncrementalGames.org: best for being found by players browsing idle games by fit
Platform: Directory · free listing and claims · optional Get featured from $30 a week
This is our site, so read this as a pitch. IncrementalGames.org lists upcoming games as well as released ones, with an upcoming page players browse for what is next, and every listing links straight to your Steam page. Submitting and claiming a game is free through the developer page, and we tag it for the things players filter by, such as length, endings, idle versus active pace and offline progress.
The optional Get featured placement shows your game in a section headed Featured, with a Sponsored label on every card, on the home page, game pages and best-of lists, for $30 a week. It suits a launch week or a Next Fest week, and payment does not affect acceptance, catalog score or recommendations.
Watch out for: A directory listing helps players find you after they hear of you; it is not a replacement for festivals and creators, which drive most wishlist spikes.
