Zip Game

Zip is a puzzle game where you connect numbered dots in sequence by swiping a path through the grid. Each puzzle has a unique solution — a Hamiltonian path visiting every cell exactly once, generated via DFS with Warnsdorff's heuristic. Features include 7 difficulty levels (Easy through Expert+++) with 100 procedurally generated puzzles each, a Walls difficulty with blocked cells, swipe-to-draw controls with backtrack support, hint system, haptic feedback, confetti on completion, progress persistence via SharedPreferences, and a dark theme with color-coded dots and difficulty accents.
