About Last Call
A free daily deckbuilder puzzle in the browser. Each day there is one fight and one turn: with the hand, action points, perks and beers you are dealt, you have to find the one set of cards that kills every enemy, with a few rounds a day to try. Days get harder through the week, and there are lessons, a share grid, streaks, stats, an archive of past puzzles and a solution you can watch. Last Call is built on the combat rules of Kegs of Eternity, a roguelite deckbuilder starring seven dwarves that Lone Piggy, a one-person studio run by Petrucio, is making in Unity and has listed on Steam for 2027; it uses that game's sound clips and is made to send players to its Steam page. Per the developer, Claude Code (Opus 5.5) built it in 11 days from an open-ended brief: it ported the game's C# combat rules to plain JavaScript, wrote an exhaustive solver and a generator that made a year of puzzles (420), each with exactly one winning set of cards, and a harness that replays every solution in the real game in the Unity Editor to check the port. “Claude Code wrote all of it”, the developer says; their part was the game it runs on, playtesting and the calls.

How it was built
Partially verifiedIn a post on r/ClaudeCode (5 Oct 2026, UTC) the developer writes that on 24 September they gave Claude Code (Opus 5.5) an open-ended challenge, “build something that sends people to my game's Steam page”, and it came back with Last Call. “Claude Code wrote all of it. My part was the game it runs on, playtesting, and the calls (“Monday is too easy”, “cards jumping between rows feels buggy”).” Per the post it built, in 11 days, a port of the game's C# combat rules to plain JavaScript and the page around it (about 5,000 lines, no framework or dependencies); an exhaustive solver and a generator for 420 puzzles; a 1,700-line rules spec citing the game's code by file and line, with 92 worked examples run as tests; a harness that plays each solution through the real game in the Unity Editor and compares the board after every move; and the lessons, share grid, streaks, archive, sound, social images, clips and itch.io build, about 14,000 lines of tooling in all. The developer says the cross-check caught a bug in its own port and that writing the spec turned up bugs in Kegs of Eternity itself. Several Claude sessions work in the repository at once (on tavern art, trailers and playtesting), and messaged each other when files changed.
Plain JavaScript ES modules with no framework or dependencies (engine, puzzles, lessons, scenes and promotion modules), about 5,000 lines for the game and page plus about 14,000 lines of tooling, per the developer. The combat engine is a port of Kegs of Eternity's C# rules; a generator and an exhaustive solver produced a year of puzzles, each with exactly one solution, and a Unity Editor harness replays every solution in the real game. Sound comes from Kegs of Eternity's own clips; per the post, one of the Claude sessions working in the same repository handles the tavern art, and in a reply the developer says one session generates art through Venice.ai. The page sends anonymous play events to the studio's own server; no AI service is called during play.

“Claude Code wrote all of it. My part was the game it runs on, playtesting, and the calls.”Verification notes: AI use, dates and the build details from the developer's post by u/petrucio on r/ClaudeCode (5 Oct 2026, 16:44 UTC) and the developer's replies, read from the Arctic Shift Reddit archive on 8 Nov 2026 (score 0; observed, not a metric). Game page, title and description from lonepiggy.com/lastcall and its scripts; studio from the Lone Piggy home page (“a one-person studio run by Petrucio”); Kegs of Eternity's developer, publisher and planned 2027 release from the Steam store API; all re-read on 8 Nov 2026. The 100% AI code share is the developer's “Claude Code wrote all of it” and covers Last Call only; this record is not about Kegs of Eternity, which the developer is making in Unity and does not describe as AI-written. Both games belong to the same developer, so no third-party IP is involved. The post says an itch.io build was released, and the page's code is written to run on itch.io, but we did not find its address, so only the web version is listed. The page's scripts were searched and call no AI services; they load their own sound files and send play counts to lonepiggy.com. No location is stated. The game was not played.
