Could you build this?
Partial The UI and standard game mechanics can easily be vibe-coded, but building an on-device Star Battle procedural board generator alongside a deterministic 17-technique human-style deduction engine requires non-trivial algorithmic constraint solving.
What it would actually take: A full implementation requires a Swift/SwiftUI frontend paired with a constraint satisfaction solver (CSP/SAT) compiled for iOS. The generator must produce valid irregular regions, solve for unique solutions, and apply human-like heuristic rules (line locks, counting, X-wings) in order of complexity to grade difficulties and output step-by-step logical hints rather than naive backtracking.
