Kata: Minesweeper 47

Have you ever played Minesweeper? It’s a cute little game which comes within a certain Operating System whose name we can’t really remember. Well, the goal of the game is to find all the mines within an MxN field. To help you, the game shows a number in a square which tells you how many mines there are adjacent to that square. For instance, take the following 4x4 field with 2 mines (which are represented by an * character):

*...
....
.*..

The Problem

I wanted to use a background gradient to represent the types of a Pokémon. There are 18 possible Pokémon types. Pokémon can have one type and some have two types. This leads to roughly 324 combinations (When a Pokémon is one type I simply double that type) or 171 combinations (18 as a triangular number) if I order the types.

The Result

Static Image: Pokemon Types Live: http://attackdex.herokuapp.com/
