Bian River Market Builder — Rebuild the Qingming Riverside Bazaar of Northern Song China

Play Bian River Market Builder — an AI-generated city-building game set in the world of Qingming Riverside. Rebuild the Rainbow Bridge marketplace of Northern Song Bianjing: lay streets, open shops, raise landmarks, and manage the economy of the greatest market city of the age, all in the soft lineart style of the Qingming scroll.
Final Product: Bian River Market Builder





Bian River Market Builder is a playable city-building game set in Qingming Riverside — the Northern Song world rebuilt in the visual language of Along the River During the Qingming Festival. You take charge of the riverside between the East Water Gate and the Rainbow Bridge: lay streets and dock planks, open tea houses and silk shops, raise pagodas and archways, and let the greatest market city of the age come back to life.
Every month brings a new cycle: money in, upkeep out, and a city that quietly asks for more. Roads lift production, riverside plots earn more, and the goals board keeps you honest — 800 residents, four landmark nodes, culture at 180, and a monthly income of 5,000 guan. The whole world was generated by AI from a single sentence, in the soft lineart, pastel palette of a silk scroll.

Game Features
- AI-Generated World & Narrative — the entire world was created by an LLM from a single seed sentence: characters, locations, events, factions and lore. Every building you place carries a story written by AI (deepseek-chat world narrative).
- Bianjing Economy Simulation — CASH, POP, HYPE, BIZ, CULTURE and TRAFFIC meters tick every month. Balance upkeep against income and grow from a lonely dock to a humming river market.
- Build the Rainbow Bridge Market — bluestone streets, loess lanes, riverbank paths and dock planks first, then shops, residences and river works along the Bian River.
- Qingming Festival Flavor — festival goods, paper horses, wine jars, tax slips, cargo permits and fire-bucket rules — the objects of the scroll become the items of the game.
- Landmarks & Famous Sites — raise the Rainbow Bridge, gate towers, drum towers, pagodas and market archways to turn a market into a famous city.
- Browser Playable — runs directly in your browser, no download needed. Place a building and watch the scroll come alive instantly.

Production Process Breakdown
AI receives the seed prompt "做一个完全还原清明上河图美术风格的北宋世界" (build a Northern Song world in the full artistic style of the Qingming scroll) and generates the Qingming Riverside world — 18 atom cards: characters (4), locations (5), events (3), lore (3), factions (3). Each card carries original descriptions and cover art.
AI designs the builder game from the atom cards: economy rules, building palette, monthly cycles and goal gates. All art assets — item spritesheets, building sprites, scene art — are generated by image models from structured prompts.
Game built and published with one click, instantly shareable online. Runs directly in the browser — no install, no login wall, just build and watch the scroll fill with life.
