The Seven Bridges of Hashiwokakero

A game made for GMTK Game Jam

"Joined Together"

You must join the islands of Hashiwokakero (lit. "build bridges") together, there are rules to where bridges can be built though... see if you can beat all 11 levels.

The game draws inspiration from Hashiwokakero logic puzzles, and the Seven Bridges of Königsberg mathematics problem.

Controls

• Build/Remove Bridge - Mouse (and maybe touch)
• Quit - Escape

Bridge Building Rules

** the game tries to teach the rules as they are used, but this list can be used for reference **

• Bridges are built from one island to a different island along the hexagonal grid lines
  
• Islands without any other rules can have any number of bridges coming from them
• Islands with some number of required or optional bridges cannot have more bridges than required + optional
  
• All islands with any number of required bridges must be connected to a single bridge system (there cannot be isolated island groups)
  
• Each House on an island requires one bridge connected to that island
• Each Inn on an island requires two bridges connected to that island
• Each Keep on an island requires three bridges connected to that island
  
• Each Tree on an island allows one optional bridge to be connected to that island
