  How to play:
Left side you can see a matrix of 4*5 tiles. Every tile has 2 properties: a color and a figure.
Find a tile which properties appears not (0) or as few as possible (n) in the same line.
Click this tile, it will be replaced by another tile.
The goal is: all the tiles in a line must have the same color or the same figure.
You start with 100 points. You get 5 points for every right tile.
You loose 10 points for every wrong tile and a better tile will be marked.
Every second 1 point will be subtracted. Good luck!
Extended goal 1: build all lines with matching colors (figures).
Extended goal 2: build the lines with matching color and figure.
