Collaborating with King to Deliver High-Quality Content for Diamond Diaries Saga

How Amber built a dedicated level design team to deliver consistent, live-ready content at scale.

Creating thousands of levels for a live puzzle game means finding new ways to keep the experience fresh without losing sight of quality, progression, or the game's original vision.

Working closely with King, Amber developed a scalable level design pipeline for Diamond Diaries Saga, combining weekly delivery, KPI-driven iteration, ongoing balancing, and close collaboration around the player experience. Over the course of the partnership, the team delivered more than 5,500 live levels while continuously adapting content and workflows as the game evolved.
