Could you build this?
Partial Generating solvable Suguru boards client-side that are guaranteed to have unique solutions and rigorously classified by human deductive techniques requires custom constraint satisfaction solvers and formal puzzle generation logic.
What it would actually take: Requires writing an offline backtracking constraint satisfaction solver and logical deduction engine in Swift/C++. The generator must incrementally apply specific human-solvable deduction techniques (like isolated groups, pairs, and block intersections) rather than brute force to accurately grade puzzle difficulty. The hard part is generating high-difficulty valid boards with unique solutions fast enough on a mobile CPU without freezing the UI.
