Overview

Dim Sum Queens is a mobile puzzle game built around logic-puzzle mechanics, with daily puzzles, multiple game modes, and backend-driven progression. I worked on the puzzle systems and the backend integration that powers rewards and progression.

My Contribution

I built the puzzle generation system, the hint system, and the backend integration for progression and rewards, working within the broader Dim Sum Games team.

Technical Challenges

  • Generating puzzle boards that are guaranteed to have exactly one valid solution, at scale, without expensive brute-force search.
  • Designing a hint system that stays contextually useful as the player fills in the board, without ever suggesting an invalid move.
  • Tying puzzle progression, daily puzzles, and rewards to a backend so player state stays consistent across sessions and devices.

Solutions

  • Built a generator with single-solution validation baked into the generation step, rejecting boards early instead of solving-and-checking after the fact.
  • Built hint logic that re-evaluates board state on demand and only surfaces hints consistent with the unique solution.
  • Integrated PlayFab for backend progression, account rewards, and daily puzzle delivery, with Game Center integration for platform-level features.
