Partner games come first in this list — we may earn a commission if you start playing through these buttons. Inside each group the stated criteria decide; see “How we ranked this” below.
Eleven free-to-play adult games that are live on Steam right now, and which ones to try first. The order rewards developers who keep posting updates, then wider platform support, then a longer run on Steam — so games that are still being looked after rise above ones that went quiet. No scores, no invented promo codes.
How we ranked this
Partner games come first; within each group, three signals decide in order, each breaking ties in the one before:
- 1. Update activity — the date of the game's latest Steam announcement, newest first.
- 2. Platform breadth — Windows, macOS and Linux beat Windows and macOS, which beat Windows only.
- 3. Time on Steam — the earlier release date ranks higher.
Not ranked: Lust Frontiers, Lust Age, Nudus and Harem Villa, which are not out on Steam yet — see Coming soon below. Isekai: Waifu Overlord joined the ranking after its Steam release on September 25, 2026.
Partner games — the ones we earn a commission on, listed on our About page — come first; within each group the order follows the criteria above. No game pays for its position.

Lust Goddess posted four announcements on October 1, 2026 alone: an October roadmap, a Halloween Festival, the three-mercenary event “Orbital Intercept” and a Commander week with Wanda and Desiree. Everlusting Life and Isekai: Waifu Overlord posted that day too, on the same two platforms, Windows and macOS, so time on Steam decides — and Pochemu LTD's flagship has been live since February 21, 2024, longer than any other game here.
Its dozen posts from September 16 to October 1 also brought three Commander pairs, three mercenary events and a Virtual Maze story mission. Steam lists 53 paid DLC, second only to Everlusting Life.
Best for: Players who want the longest-running game here.
-
Everlusting Life's October 1, 2026 post opened an Awakening event for the maiden Kayra — the same day as Lust Goddess and Isekai: Waifu Overlord, on the same two platforms. Live since May 8, 2025, Pochemu LTD's auto-chess RPG sits between them on time on Steam, so it ranks second.
September ran on a weekly rhythm: Awakening events for Chainkiss, Snezhana and Iris, Time Rift memory chapters on September 3, 11, 18 and 25, and Version 7.0.0 on September 21, which added Conquest, a new mode with Officers, Guilds and player competition. Steam lists 55 paid DLC — the deepest DLC catalog on this list.
Best for: Auto-chess fans who want new characters every week and the biggest DLC catalog.
-
Isekai: Waifu Overlord's latest post, a PvE event for the princess Rosalind von Eisenthal, went up on October 1, 2026. It shares Windows and macOS with the two games above, but it has been on Steam only since September 25, 2026, so it comes third.
Passion Panda and GreenT's village-builder gives you a settlement and a squad of heroines, with relationship levels, dates and animated 18+ scenes. The Steam build arrived with 22 interface languages, full English and Russian voice acting, 66 achievements and no DLC, with events running from launch day. It has been playable on Nutaku since July 16, 2026, also runs as a standalone browser build, and its Steam page is not available in Germany.
Best for: Players who want the newest release, with voiced heroines.
-
Slut Squad's latest Steam post, a pirate-themed raid starring Captain Tempest, went live on September 25, 2026 — a day newer than the latest posts of Horny Villa and Passion Industry, which puts it fourth. It lists Windows and macOS and has been live since December 1, 2025.
Passion Panda and GreenT's idle-merge heist game ran short character events almost weekly from late April to late June 2026, with two Battle Passes alongside, then went quiet for ten weeks until “Dick Search Girl: Detective” (August 28–31). Steam lists no DLC and 20 interface languages.
Best for: Fans of idle-merge heists and short character events.
-
Horny Villa's latest Steam post, an Oktoberfest event running September 24 to October 7, 2026, shares its date with Passion Industry's latest update. Platform breadth settles the tie: Steam lists Windows, macOS and Linux for Horny Villa — the only native Linux build in this catalog.
GreenT and publisher Nutaku Publishing have kept a near-weekly event pace since at least June 2026; a space-themed Battle Pass with the Mythic heroine Nyoki (September 15–October 12) runs alongside Oktoberfest. Steam lists one DLC, a paid artbook; the game has been live since November 7, 2024.
Best for: Players who want Linux support and a themed event every one to two weeks.
-
Passion Industry's September 24, 2026 update ties Horny Villa's date, but BarHat Games' merge-and-dating sim lists two platforms, Windows and macOS, to Horny Villa's three, so it follows one place behind. It has been live since December 8, 2025.
That update introduced the succubus Lustia, a Surplus Lottery for stockpiled resources and a building cap raised from level 5 to 10. It keeps a monthly heroine rhythm that has held since March — Lumi, Hana, Bianca, Celeste, Victoria, Anupet, then Yumin and Scarlett together on August 27. Steam lists no DLC.
Best for: Players who want a monthly new heroine and no paid DLC.
-
Mafia Queens heads the rest of the list after a busy September. NIFCOR KFT's match-3 title, live since August 14, 2026 for Windows and macOS, pairs board-clearing puzzles with an interactive-comic crime story.
After four quiet weeks, a major update on September 11 added the heroine Chloe with three new scenes and a new adventure, along with a Luck Challenge featuring Mia and Rosie; three new Strip Time girls followed on September 17 and an Oktoberfest trio on September 24. Steam lists no DLC.
Best for: Match-3 fans who want a crime-comic story that added characters weekly in September.
-
Asomgames' card-battle game posted its “Velvet Smoke” event on September 17, 2026, the same day as Lustquake Legion's latest fix. Both list Windows only, and Harem of Lust: Battle Cards has been live since July 16, 2025, so it ranks ahead.
Since March 2026 a themed event has landed roughly every two to four weeks, from Spring Break (March 19) to Sexologist (August 20) and then Velvet Smoke, which brings back a fan-favorite card alongside a skin and a profile frame. Published by Passion Panda Publishing, it lists no DLC.
Best for: Deckbuilding fans who want frequent themed events on top of card combat.

Lustquake Legion's latest Steam post, a September 17, 2026 fix for event progress that could reset, came the same day as Harem of Lust's Velvet Smoke event. Both are Windows-only, and Amazed Studio's game, released April 27, 2026, is the younger of the two, so it ranks ninth.
Between May 22 and July 21 the developer posted at least twelve announcements, from small hot-fixes to a June 2 rework of PvP and PvE combat. In this crime-and-relationship idle game, buildings generate income and loot boxes supply new crew. Steam lists no DLC.
Best for: Incremental-game fans who like loot boxes, PvP and a crime theme.
-
Wet Wealth's latest Steam post, the “Wet Hospital” update of August 8, 2026, is more than five weeks older than the latest posts of every game above it, which places it tenth. It lists Windows only and has been live since June 12, 2026.
That update was a large one: Lewd Labs added a hospital location, three new characters, a Match-3 mode alongside the slot-spin loop, a Battle Pass and a “Hot Shot” event. A July 27 Waifu Gala tie-in carried a Steam-only promo code, since expired. Steam lists no DLC.
Best for: Slot-and-collection fans who want a recently expanded game.
-
Milf Solitaire closes the list because its only Steam announcement is the release post of April 30, 2026; nothing has followed it, even though it has been on Steam longer than three of the games above it.
U Master's patience-card game pairs table-clearing with a light, choice-driven romantic layer. Steam lists Windows and macOS, 22 interface languages — tied with Isekai: Waifu Overlord for the widest language reach in the catalog — and no DLC.
Best for: Players who want a relaxed card session, not an event schedule.

What 'free' means on this list
All eleven games install and run at no cost: Steam lists a $0 price for each one. Inside, money still matters. Everlusting Life carries 55 paid DLC, Lust Goddess 53 and Horny Villa one, a paid artbook; the other eight list none, and every game here has an in-app-purchases tag on Steam. Some add event-only currencies — Lust Goddess's roulette tokens, Everlusting Life's Awakening Coins — that the developers' own posts say disappear once that week's event ends. None of that locks the base game behind a purchase.
How to pick
By genre: Lust Goddess and Everlusting Life are card-battle and auto-chess RPGs from the same developer; Horny Villa and Passion Industry are merge games; Slut Squad is an idle-merge heist game; Isekai: Waifu Overlord is a village-builder with dating; Wet Wealth runs on slot spins; Mafia Queens is match-3, Milf Solitaire: Lust Collector solitaire, Harem of Lust: Battle Cards a deckbuilder and Lustquake Legion an idle gang-management sim.
On platforms, only Horny Villa ships on Linux; Wet Wealth, Lustquake Legion and Harem of Lust: Battle Cards are Windows-only, and the rest run on Windows and macOS.
Coming soon
Lust Frontiers, from Pochemu, has a Steam page marked coming soon, with no release date yet. Lust Age and Nudus, both from Hooligapps, are also marked coming soon on Steam — Lust Age with only “2026” as its release window, Nudus dated November 11, 2026 — and each has had a separate Steam demo since June 14, 2026; both already run as browser games on the developer's own sites. Harem Villa runs only in the browser. Each joins the ranking once it ships on Steam, as Isekai: Waifu Overlord did.
