Show HN: FuseCells – a handcrafted logic puzzle game with 2,500 levels

https://apps.apple.com/us/app/fusecells-logic-grid-puzzle/id6754704139
12•keini•1h ago
Hi everyone, I built FuseCells, a minimalistic logic puzzle game where every level is handcrafted (no procedural generation). It started as a personal challenge to design a clean rule-set and scale it to thousands of puzzles without losing difficulty balance.

What’s unique: • 2,500 handcrafted levels across multiple grid sizes • Deterministic logic — no guessing required • A rule system inspired by constraint-solving and path-finding concepts • Daily challenges and global progress tracking • Fully built as a solo dev project

Technical notes for those curious: • Level generation tools I wrote validate solvability using a custom constraint solver • Difficulty is estimated via step-count of the solver • The game is optimized to run smoothly on low-end devices • Designed first for iOS, now fully adapted for iPad as well

I’d love feedback from puzzle lovers, game designers, and anyone interested in handcrafted logic design. Here’s the App Store link: [inserați linkul]

Thanks for reading — happy to answer any technical questions!

Happy to share some technical details for anyone curious:

I wrote a custom solver to validate each puzzle and estimate difficulty. It works by applying deterministic constraints until the board reaches a stable state. If anyone is interested, I can share the logic flow or even open-source the validator.

Also curious: does anyone here have experience balancing handcrafted puzzle difficulty at scale?
