Hashi
Every island, together.
Bring a little world together
A still jade pond holds a handful of ceramic islands. Each island tells you how many bridges it needs. Build straight wooden crossings to the nearest island along a row or column, using one or two bridges on a route. Follow the numbers until you can travel from any island to every other one.
Tap an island and its neighbour, or drag between them. The same connection cycles through one bridge, two bridges and no bridge. The Rule out pencil records routes you have excluded; those notes can be changed at any time. Undo takes back one connection. Restart gives you a clean pond with the same clues.
A certain first step
- Count the routes. An island showing 4 with only two possible neighbours needs two bridges to each. An island showing 3 in the same position needs at least one bridge on both routes.
- Respect a completed number. When the bridges already meet an island's number, its other routes must stay empty. A green check confirms the count, not that your whole placement is necessarily right.
- Read the crossing. A built bridge rules out a route passing across it. Islands block bridges too: you cannot skip a nearer island to reach one behind it.
- Keep the world connected. A route may be the only remaining link between two groups. It needs at least one bridge even before its exact count is known.
Questions
What are the rules of Hashi?
Connect numbered islands with horizontal or vertical bridges. Each number counts the bridges touching that island. Two islands can share at most two bridges. Bridges cannot cross or pass through islands, and every island must belong to one connected network.
How do I build a double bridge?
Tap one island and then its nearest neighbour in the same row or column, or drag between them. Connect that pair again for a second bridge. Connect it a third time to remove both. A double bridge counts as two for each island.
What does Rule out do?
Rule out adds an optional pencil cross to a route you have excluded. Select the same pair with Rule out to erase the note. Build bridges can replace a note with a bridge. Notes are not required to finish.
Can the bridges make a loop?
Yes. Loops are allowed. The important requirements are the island numbers, no crossings and one network connecting every island. A locally complete pair separated from the other islands is not a finished puzzle.
Are the puzzles unique and solvable without guessing?
Yes. Each original puzzle passes an exact one-solution check and a separate logical solver. Easy uses number capacities; Medium adds crossing deductions; Hard also requires reasoning about the connectivity of groups. Hints explain a deduction from the public clues, rather than revealing a stored answer.
Does Hashi count towards my daily streak?
Yes. A server-verified daily solve counts towards Today and your streak from November 2, 2026. Practice does not change daily progress or add a daily collectible. Earlier preview results stay in your collection without becoming official days.
Classic rules, original little islands
Hashi is also called Bridges or Hashiwokakero. The classic rules are described by Nikoli. These puzzles, ceramic islands, wooden bridges and miniature archipelagos are independently made for PuzzleGame.win. We check every admitted board for a single solution and a complete logical route.
Practice has 30 boards per level, with personal bests stored in this browser. The shared daily puzzle resets at 00:00 UTC. A verified daily solve earns a named miniature island scene; an unverified local solve keeps a plain one. The collectible's appearance comes from the date, never the solution. A daily score begins at 3,000, loses four points per second and 300 per logical hint, and stays at or above 100. Server verification lasts up to 30 minutes from your first move.
