About Boomstick City
Boomstick City is a free-to-play head-to-head card game set in a city bolted together from the ruins of the end of the world, where neighbourhood associations and unionised demolition crews fight to survive. Instead of grinding down a health bar, two crews fight over one shared board: you spend Volts, which ramp up every turn, to play Survivors, Gear and Events, win fights to take Territory Points, and raid the enemy's Stash for extra points when their board is clear. The first crew to 15 points wins; there is no turn limit, but running out of cards costs a point a turn, and most matches last around eight turns. There are four crews, all free from the start: Scrapwright (salvage and recursion), Powderkeg (explosions and aggression), Hearth (defence and going wide) and Glow (radiation and attrition), and the developer counts more than 130 cards. Matches are online 1v1, casual or ranked, after a guided first match. Card packs and cosmetics can be bought with in-game currency or real money; the developer says they are never required to win and publishes the pack odds. It runs in desktop and mobile browsers with no install, and needs an account. The developer, posting as u/Phinguin, says it was their first serious web project and that it is 100% vibe coded, with Claude Code driving the whole build and Opus 4.8 writing the code.
How it was built
Partially verifiedIn a post on r/vibecoding (25 Jul 2026, UTC) titled “I made a multiplayer CCG 100% vibe coded!”, the developer lists the stack: “Claude Code as the driver for the whole build”, “Opus 4.8 for the coding itself” and “Fable for auditing and checks”, with Colyseus for the multiplayer server, GPT for the card art and ElevenLabs for the voices. The developer, normally a mobile developer, says it was their first real web project and that they set out to see how far pure vibe coding could take it: “all the way, apparently.”
Built with Claude Code driving the work, Opus 4.8 writing the code and Fable used for audits and checks, per the developer. Online matches run on a Colyseus multiplayer server; the browser client also contains a computer opponent, which is scripted game logic with no network calls. The card art was made with GPT and the voices with ElevenLabs; both ship as files, and nothing is generated during play. The developer designed for desktop first and then cut back the interface for phones, and says card balancing took the longest.

“I made a multiplayer CCG 100% vibe coded!”Verification notes: AI use and the stack from the developer's post on r/vibecoding by u/Phinguin (25 Jul 2026, 12:42 UTC) and a reply under it, read from the Arctic Shift Reddit archive on 7 Nov 2026; the post links boomstickcity.com. The 100% AI code share reflects “100% vibe coded” with Claude Code and Opus 4.8 credited for the code. Rules, crews, modes, pricing, the account requirement and the developer name from the official site, its FAQ, pack-odds page, press kit and terms of service (last updated 17 Jul 2026), read on 7 Nov 2026; the release date is the first devlog entry, “The city's open” (17 Jul 2026). The card count (130+) is from the post. The play client connects only to the game's own Colyseus server and Stripe; its bot opponent is local game logic, and no AI services are called. The developer's FAQ compares the game with Hearthstone; that comparison is the developer's own. Team size is not stated. The game was not played.
