💡 Inspiration

Classic connect-the-dots flow puzzles are timeless, but they often lack visual depth, soothing aesthetics, and long-term algorithmic variety. We set out to create Flow Link — a premium puzzle experience that blends dreamy pastel 3D visuals with deep, mathematically verified procedural puzzle generation.

🎮 What it does

  • Core Gameplay: Connect pairs of matching color dots across grids ranging from 5x5 to extreme multi-path grids, with a strict rule: 100% of the grid cells must be covered.
  • Massive Content: Over 20,000 unique levels spanning 10 distinct difficulty modes (2,000 levels per mode).
  • Global Accessibility: Fully localized across 9 languages (English, Thai, Japanese, Korean, Simplified Chinese, Indonesian, Spanish, French, and German).
  • Sensory Experience: Dreamy celestial visual effects, calming audio design, and smooth haptic feedback designed for mindful, stress-free logic solving.

🛠️ How we built it

  • Frontend & Engine: Built using Flutter & Dart for smooth 60fps cross-platform performance on iOS and Android.
  • Level Generation & Verification: Custom procedural scaling and backtracking algorithms that verify single-path solvability and grade difficulty scientifically.
  • Localization Infrastructure: 2-tier robust translation architecture with placeholder parity testing and zero UI-overflow guarantees.

🏆 Accomplishments that we're proud of

  • Successfully verified and packaged 20,000 playable levels without any impossible states.
  • Published live globally on both Apple App Store and Google Play Store.
