Hashi Puzzle Online Free
Connect every island with bridges. Each number says how many bridges it needs, bridges can’t cross, and all the islands must join up.
Drag from an island towards another to add a bridge: one, two, then none. You can also tap the water between them.
What is Hashi?
Hashi is a logic puzzle where you connect numbered islands with bridges. Each island needs exactly as many bridges as its number, bridges run straight across or down, two islands can share one or two bridges, no bridges may cross, and in the end every island must be joined into one group.
Its full Japanese name, Hashiwokakero, means “build bridges”, and it was first published by Nikoli. It’s also known as Bridges or Chopsticks. The numbers are small, so children who can add to 8 can play. For another puzzle about connecting a grid, try Slitherlink or Masyu.
How to play Hashi Puzzle
- Each circle is an island. Its number says how many bridges must end at it.
- Bridges run in straight lines across or down between two islands, over empty water. Two islands can be joined by one bridge or two, never more.
- Bridges can’t cross each other or pass over another island.
- When you finish, all the islands must be connected into one group, so you can travel from any island to any other.
- Drag from an island towards a neighbour to add a bridge. Do it again for a second bridge, and a third time to remove them. Tapping the water between two islands does the same.
- Every puzzle is made fresh and checked to have exactly one solution, so it can always be solved by logic without guessing. Use Hint if you’re stuck, and pick a size at the top of the board.

Tips for Hashi
An island whose number is twice its number of neighbours needs two bridges to each: an 8 with four neighbours, a 6 with three, or a 4 with two.
Count an island’s neighbours. If the number is twice the neighbours minus one, such as a 5 with three neighbours or a 3 with two, every neighbour gets at least one bridge.
Two 1s next to each other can’t be joined (they’d be cut off from everything else), and neither can two 2s with a double bridge.
Islands light up when they have all their bridges, so you can see at a glance which ones still need work.
Hashi Puzzle questions and answers
How do you play Hashi?
Connect the islands with straight bridges so each island has as many bridges as its number. Two islands can share up to two bridges, bridges can’t cross, and all the islands must end up connected.
Is Hashi the same as Bridges?
Yes. Hashi is short for Hashiwokakero, Japanese for “build bridges”. The puzzle is also published as Bridges and Chopsticks, with the same rules.
Is Hashi good for kids?
Yes. The numbers only go up to 8, and working out how many bridges are left is good addition practice. Children from about 8 can enjoy the 7 × 7 puzzles.
Does every Hashi puzzle have one solution?
Yes. Every puzzle here is checked by a solver when it’s made, so there is exactly one way to place the bridges.
