Snake and Ladders Kata

A windows console app implementing the snakes and ladder game as outlined here http://agilekatas.co.uk/katas/SnakesAndLadders-Kata. Unit tests use NUnit and require an appropriate test runner.

Approach

Due to the well defined nature of the game I decided to use a strict TDD approach. I let the features guide my creation of unit tests, with the unit tests dicatating the required classes and their structure.

Key design decisions and alternatives

My main consideration was around how to represent the board and it's associated tokens. Initially I imagined a 2-d 10 x 10 array would be a good representation of the board. However once I started formulating my tests it became apparent that the board was in esscence a 1-d array with a length of 100; also rather than using the Board to keep track of Token locations it was better for each Token to track it's current location.

Evolving in the future

Apart from implementing the outstanding features (Multiple Players + Computer Controlled Players) I'd add more constraints around where snakes and ladders can start/end, to:

• avoid overlapping snakes + ladders
• stop snakes and ladders starting or ending outside the beginning or end of the board.
