dougo/pathpuz

Path-based logic puzzles.

PathPuz

Play path-based logic puzzles (like Monorail, Alcazar, Slitherlink) in a web browser.

Usage

Currently, Monorail is the only puzzle type implemented.

Monorail

The goal is to connect all the dots with a single closed loop that does not cross itself. Some puzzles will start with some dots already connected.

Click (or tap) between two dots to connect them with a line. Click again to mark a line absent, i.e. to indicate that two dots cannot be connected directly. Click a third time to go back to being undetermined.

Click on a dot to auto-complete it: if there is only one way for the loop to go through the dot, the appropriate lines will be filled in; if there are already lines going into and out of the dot, then the other lines will be marked absent.

The Hint button will find a dot to auto-complete, if there are any, and complete it.

The Auto-hint option will auto-complete all dots whenever possible.

Installation

Add this line to your application's Gemfile:

gem 'pathpuz'

And then execute:

$ bundle

Or install it yourself as:

$ gem install pathpuz
