 The game called Flood-It has been around for some years. There are many
 clones and variants available for desktop and mobile platforms.
 
-The game board is a grid squares, colored at random in multiple colors. In each
-move the player changes the color of the "start square" (top left corner) and
-all squares of the same color that are connected to it. The objective is to
-fill the entire grid in a single color using as few moves as possible.
