Cómo resolver Hashi
Conecta las islas con puentes
¿Quieres otra partida de Hashi, el puzzle que los juegos diarios de LinkedIn hicieron popular? Aquí es ilimitado: tableros gratis generados al momento, tres niveles de dificultad y solución única garantizada.
Cómo jugar a Hashi
- Une las islas numeradas con puentes horizontales y verticales.
- El número de una isla indica cuántos extremos de puente deben tocarla.
- Como máximo dos puentes entre un mismo par, y los puentes nunca se cruzan.
- Arrastra de una isla a otra para trazar un puente; repite para un puente doble. Toca un puente para eliminarlo. Todas las islas deben formar una sola red conectada.
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.
FAQ
- ¿Hashi es gratis e ilimitado en LinkMyPzzl?
- Sí. Cada tablero de Hashi se genera al momento en tu navegador: juega cuanto quieras, gratis y sin cuenta.
- ¿En qué se diferencia del puzzle diario de Hashi?
- La versión diaria popularizada por LinkedIn ofrece una cuadrícula al día. LinkMyPzzl genera tableros ilimitados y te deja elegir la dificultad.
- ¿Cada tablero de Hashi tiene solución única?
- Sí. Un solucionador verifica cada tablero generado: siempre hay exactamente una solución.
- 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.
