What are the rules of Hashi?
Hashi asks you to connect numbered islands with bridges so each island has exactly as many bridges as its number. Bridges run straight across or up and down, never cross, and at most two join any pair. Finally, every island must link into one connected group.
The puzzle comes from the Japanese publisher Nikoli, whose title Hashi o kakero means "build bridges". Wikipedia's Hashiwokakero entry dates its first appearance to Puzzle Communication Nikoli issue 31 in September 1990. Here are the rules in full:
- Bridges run horizontally or vertically between two islands.
- Bridges never cross each other or pass over an island.
- Two islands share no more than two bridges.
- Each island's number equals the bridges touching it.
- All islands end up joined in one group.
Count, connect, never cross: one answer per board.
Honest limits
Sumbriska is not a Hashi app. We made it, and its bridges work differently: each island shows a target sum, and you flip bridges to send numbers between islands until every total lands. If you only want classic Hashi on a phone, our games like Hashi bridges page compares apps that play it straight.
Six boards is a small pack. They run from easy to medium, with 8 islands on a 7×7 grid and 12 on 8×8. Seasoned solvers will want bigger grids.
