About Soft 17
SOFT 17 is a blackjack roguelite for Windows. You play real hands against the dealer (hit, stand, double, split), and a winning hand earns chips multiplied by the MULT, which your items push higher; every table shows the score to reach and how many hands you get. After each table you clear, the dealer deals three rewards and you keep one, and each floor has a shop. A climb has three floors, each closed by a boss, and then The House; a missed table earns a warning, and too many warnings get you thrown out. What a climb earns goes down to your cellar, the Circle, even when you lose: furniture there helps every later climb, beaten bosses move in and lend their talent, and seven gambling games set up shop, from the slot machine to the shell game. The other three casinos change the rules of blackjack, for example both dealer cards face up, a shoe with no tens, or two hands that swap their second cards, across twelve difficulties. Act II moves to poker: four houses, four variants, and you cheat by swapping cards under the dealers' eyes. Two to four players can share a table online through Steam or over a local network. The developer, who publishes as Berko and says they have no development background, says the foundations of the code were largely built with Claude: “I directed, tested, and iterated; I didn't hand-write the logic.” The visuals and sounds are generated by the game's code rather than imported as files; the Steam disclosure says generative AI made eight menu icons, the store artwork and part of the text and its English translation. A free demo has been on Steam since 29 Sep 2026; the full game is listed for 25 Feb 2027.

How it was built
Partially verifiedIn a post on r/aigamedev titled “Shipped a free Steam demo: 100% AI-written code, 0 AI images (all visuals procedural), $0 budget, solo, no dev background” (30 Sep 2026, UTC) the developer writes: “The foundations of the code were largely built with Claude. AI. I directed, tested, and iterated; I didn't hand-write the logic.” The post adds that the translations were done by AI, and that AI did best on rule logic and edge cases and struggled most with UI polish and game feel. In replies the developer says they used “only opus 5 and 5.5 when it came out” on a “30$/month claude subscription only”. Which Claude app was used is not stated.
Solo project by a developer with no development background, who directed, tested and iterated while Claude wrote the logic. The cards, tables, dealers, interface and sounds are drawn and synthesised by the game's code while it runs rather than imported as files. Per the Steam AI disclosure, generative AI made eight interface icons in the main menu, the store-page artwork and part of the in-game text and its English translation, all produced in advance from written briefs and then reviewed, edited and assembled by hand; the developer's post also says the translations were done by AI. The engine is not stated. Steam lists Windows 10 (64-bit), DirectX 11 and 450 MB of storage.

“I directed, tested, and iterated; I didn't hand-write the logic.”Verification notes: AI use from the developer's post on r/aigamedev by u/DOFFY292 (30 Sep 2026, 12:56 UTC) and the developer's replies, read from the Arctic Shift Reddit archive on 8 Nov 2026; the post links the Steam page. The post title says “100% AI-written code” while the body says the foundations of the code were “largely” built with Claude, so no code share is recorded. The tool is recorded as Claude (the developer writes “Claude” and a Claude subscription, not Claude Code). The “$30/month” figure is quoted as the developer wrote it. Store facts from the Steam store API and store page on 8 Nov 2026: developer and publisher Berko; full game (app 5284030) coming soon with a release date of 25 Feb 2027, Windows only, no price shown; demo (app 5295910) released 29 Sep 2026, free; categories include single-player, online and LAN co-op. Steam shows no reviews for either app. The developer is identified only as Berko (Steam) and u/DOFFY292 (Reddit); location is not stated. Steam lists age ratings of 12 (Germany, for violence) and 10 (Brazil). The game is about casino games; nothing in the sources mentions real-money play, and the store does not list in-game purchases. In the comments, one player reported a crash on launch and the developer said they would look at it. The game was not played and its build was not checked for AI service calls; neither source describes AI used during play.
