게임 방법: Hashi
- Join the numbered islands with horizontal and vertical bridges.
- An island's number is how many bridge ends must touch it.
- At most two bridges may link the same pair, and bridges can never cross.
- Drag from one island to another to draw a bridge; drag again for a double bridge. Tap a bridge to remove it. Every island must end up connected into one network.
How to solve Hashi: techniques that work
Count neighbours before anything else. An island's number is spread across at most two bridges per neighbour, so an island showing 2k with exactly k neighbours must run a double bridge to every one of them: a corner 4 with two neighbours is fully forced, as is an edge 6 with three. These "saturated" islands are free moves — play them all first.
One step weaker but just as useful: an island whose number is 2k−1 with k neighbours must connect at least once to every neighbour. That single guaranteed bridge is often enough to block a crossing elsewhere and cascade into the next deduction.
Keep the network connected. All islands must end up in one web, so a bridge that would seal off a finished sub-network — say, a 1—1 pair on the edge linking only to each other — is illegal even if the numbers allow it. Late in a board, connectivity is usually the argument that decides the last few bridges.
Common mistakes
Forgetting that bridges block each other: a bridge is a wall for every perpendicular route. Players plan two bridges that cross and only notice when the second refuses to draw.
Overloading a pair. However large the numbers, two islands can share at most two bridges — an 8 next to an 8 still exchanges only a double bridge and needs other neighbours for the rest.
From easy to hard
More islands mean longer chains between forced moves. On hard boards alternate systematically: saturate the full islands, then run the connectivity check, then look for almost-saturated ones. Hashi (Hashiwokakero, "build bridges") rarely needs more than these three ideas.

- 모든 Hashi 보드에 유일한 정답이 있나요?
- 네. 솔버가 생성된 모든 보드를 검증합니다. 정답은 언제나 정확히 하나입니다.
- Can bridges cross each other?
- Never. Bridges run straight horizontally or vertically and act as walls for perpendicular bridges — planning around crossings is the heart of the puzzle.
- How do I delete a bridge I've drawn?
- Just tap or click the bridge itself and it disappears. Drawing works by dragging from one island to an aligned neighbour; a second drag makes the bridge double.
