The object of the game is to spill colors among squares to create the "goal" color. Each color contains red, green, and blue contents on a scale of 0 to 8. Hover over a square to see its color content and click to select it. Once a square is selected, press "R", "G", or "B" to choose your mode and then "W", "A", "S", or "D" to spill that color into an adjacent square. Spilling will transfer as much of the color as possible until the maxmimum of 8 is filled. For example, spilling a square with 5 red into a square with 6 red will result in the first square having 3 and the second square having 8. Spill wisely.
