Inspiration

We wanted to build a small tile-placement strategy game that works directly on Reddit. The idea is simple, a daily puzzle that everyone can play together and compete for the highest score.

What it does

Miniature Borough is a daily tile-placement puzzle game. Each day, a new 6×6 grid is generated with a unique seed. Players get 10 turns, and each turn offers two tile choices (🏔️ Mountain, 🌲 Tree, 🌾 Farm, 🏰 Castle, 🏠 House) with row or column placement limits.

Tiles score based on their surroundings: trees score near mountains, farms score near grass, houses score based on different neighbors, and castles score by their grass-path distance to houses. Players get three attempts per post to achieve their best score.

How we built it

• Built as a Devvit app with a React-based client for the splash screen and game UI.
• Backend runs in Devvit’s serverless environment.
• A scheduled Devvit job automatically creates the daily post.
• Uses a deterministic, seeded puzzle engine.
• Game logic (scoring, grid generation, placement validation) lives in a shared module used by both client and server, keeping everything in sync with zero duplication.

Challenges we ran into

Deterministic puzzle generation - ensuring all players see the exact same board and tile options required carefully sharing a seeded PRNG between client and server.
