The Four Color Problem is a strategy game where you take turns with an opponent to fill a map like screen with your own colors. You will be playing as both Black and Gray, while the CPU opponent will play as Green and Orange. You'll always take the first turn, so make sure to strategize your moves before making them. Colors should be alternated - you can't color an area if an adjacent area has been marked with the same color. This adds to the strategy part of the game as you'll need to think about how you'll use your 2 colors to take the biggest areas on screen.
