Bridges Game Guide

📖 About

Bridges (Hashiwokakero) is a connecting puzzle where you build a network of bridges between islands. Each island displays a number indicating how many bridges must connect to it. Bridges run horizontally or vertically, can be single or double, and never cross. All islands must be connected into a single network. A satisfying test of spatial planning!

🎯 Objectives

Connect all islands with bridges so that each island has the correct number of bridge connections, no bridges cross each other, and all islands form one connected network.

🎮 How to Play

Click between islands to build bridges (1-2 bridges per connection). Each island's number shows required bridge connections. Bridges run horizontally/vertically and cannot cross. All islands must connect.

⌨️ Controls

Click between two islands to add a bridge. Click again to add a second bridge (double). Click a third time to remove all bridges.

⚙️ Game Mechanics

  • Each island number indicates how many bridges connect to it
  • Bridges run horizontally or vertically only
  • Maximum of 2 bridges can connect any pair of islands
  • Bridges cannot cross other bridges
  • All islands must be connected in a single network

Features

  • Multiple grid sizes available
  • Auto-check for valid connections
  • Highlight disconnected islands
  • Undo/redo functionality

💡 Tips

  • Islands with 8 need 4 bridges in each direction
  • Corner 4s need 2 bridges in each available direction
  • Plan routes to avoid bridge crossings
  • All islands must be connected in one network

Frequently Asked Questions

What does the number on each island mean?
The number tells you exactly how many bridges must connect to that island. A 4 means four total bridge connections (which could be two double bridges or four single bridges).
Can bridges cross each other?
No, bridges can never cross or overlap. You'll need to plan alternative routes when islands block direct connections.
Do all islands need to connect to each other?
Yes! All islands must be reachable from any other island through the bridge network. No isolated groups allowed.
What's the maximum bridges between two islands?
You can place up to 2 bridges (a double bridge) between any pair of islands that can be connected horizontally or vertically.
