FuseCells

Hi everyone,

I built FuseCells, a minimalist logic puzzle game where every level is handcrafted (no procedural generation).

It started as a personal challenge to design a clean, deterministic 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 developer project

Technical notes for those curious:

• Level tools validate solvability using a custom constraint solver

• Difficulty is estimated via solver step-count

• 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.
