How to Play Zip Puzzle
- Goal: Draw a continuous path from cell 1 through every checkpoint to the final numbered cell.
- Movement: Drag or swipe up, down, left, or right to move through the grid.
- No Revisits: Each grid cell can only be visited once. Plan your route carefully.
- Walls: Some adjacent cells are blocked by walls. You must go around them.
- Checkpoints: You must pass through the numbered checkpoints in order (1 → 2 → 3 ...).
- Progression: Levels get harder with bigger grids (5×5 → 6×6 → 7×7) and more walls. Your streak and best times are saved.
