遊び方： Zip
- 数字1から最後の数字まで、数字を順番に通る1本の道を描きます。
- 道は盤面のすべてのマスを通らなければなりません。
- 道は交差できず、太い壁も通れません。
- ドラッグで描くか、道の先端と一直線上のマスをタップして一気に埋めます。通ったマスを踏み直すと戻れます。
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
- LinkMyPzzl の Zip は無料・無制限ですか？
- はい。Zip の盤面はブラウザ内でその場で生成されます。アカウント不要・無料で、好きなだけプレイできます。
- 毎日の Zip パズルと何が違いますか？
- LinkedIn で人気になったデイリー版は1日1問だけ。LinkMyPzzl は盤面を無制限に生成し、難易度も選べます。
- Zip の盤面には必ず一意の解がありますか？
- はい。ソルバーが生成された全盤面を検証します。解は常にただ1つです。
- 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.
