- 拖动绘制，或点击与路径末端对齐的格子一次填充。经过已走的格子即可回退。
How to solve Zip: techniques that work
Zip is a Hamiltonian path puzzle: one line from checkpoint 1 to the last number that visits every cell exactly once. Before drawing anything, look at the corners and edges. A corner cell has only two neighbours, so the path must enter through one and leave through the other — corners are effectively pre-drawn.
Watch for pockets. If your planned route walls off a group of empty cells, the board is already lost — every cell must be reachable by the remaining path. Good players constantly ask "can the line still get back out of there?" before committing to a turn.
Use the checkpoints as anchors and plan backwards from the final number as well as forwards from 1. The stretch between the two last checkpoints is usually the most constrained part of the board; solving it mentally first often decides the whole route. Walls block movement between adjacent cells, which paradoxically helps: each wall removes options and makes more of the path forced.
Common mistakes
The most frequent one is filling space greedily and leaving a single unreachable cell in a corner — the parity of the grid means one stranded cell can rarely be recovered. Undo early rather than pushing a doomed line.
Second: forgetting the checkpoints must be hit in ascending order. A route that touches 3 before 2 is invalid even if it covers the board perfectly.
From easy to hard
Difficulty scales with board size, wall count and checkpoint spacing. On hard boards, treat each pair of consecutive checkpoints as its own mini-puzzle and check that your segment leaves a connected region for the rest of the path.
FAQ
- 在 LinkMyPzzl 上玩 Zip 免费且无限吗？
- 是的。每个 Zip 棋盘都在浏览器中即时生成——想玩多少玩多少，免费且无需账号。
- 这和每日 Zip 谜题有什么不同？
- 由 LinkedIn 带火的每日版每天只有一题。LinkMyPzzl 无限生成棋盘，难度由你选择。
- 每个 Zip 棋盘都有唯一解吗？
- 是的。求解器会校验每个生成的棋盘：永远恰好只有一个解。
- Do I have to cover every cell?
- Yes. The path must pass through every single cell of the grid exactly once while hitting the numbered checkpoints in order — covering the numbers alone isn't enough.
- How do I undo a wrong turn?
- Drag backwards along the path to retract it, use the Undo button under the board, or re-enter any earlier cell of the path to cut it back to that point.
