Zip is a single-path puzzle. Draw one continuous line that passes through every cell on the grid exactly once, while visiting the numbered cells in order: 1 → 2 → 3 and so on. It is a relaxing but clever test of planning — no syllabus knowledge required.
Yes. A valid solution covers all cells with one continuous path that ends on the final number.
No. Each cell is used exactly once and the line never revisits a cell.
Yes — the puzzle is daily-seeded, so everyone solves the same board each day.
