Hashi Bridges Puzzle: Pontis
Connect every island
Hashiwokakero bridges puzzles: connect the islands. Daily puzzle, plays offline.
The rules
- The number on an island is how many bridge ends it needs: no more, no fewer.
- Bridges run straight, up and down or side to side. At most two connect the same pair.
- Bridges never cross each other.
- When every number is met, all islands have to hang together in one single network.
How to play here
Drag from one island to the next to build. Tapping a bridge counts it up to two, then back down.

About the game
Pontis is a Hashi game: the bridges logic puzzle also known as Hashiwokakero, Japanese for "build bridges!".
Every island shows a number, and that number is how many bridges must touch it. Link all the islands into one network without crossing any bridges, and the puzzle is solved.
How to play hashi
- Each island shows how many bridges end on it.
- Bridges run straight across or down, single or double, and never cross.
- All islands end up in one connected network.
