In Color Oil, your task is to fill the board with the same color oil. The game starts in the cell labeled S. Tap the buttons on the bottom to change the color of oil to match the surrounding cells. Do this repeatedly until all cells are of the same color. You should complete each level in a limited number of steps, which is displayed in the top right corner. Try to collect all three stars for each level. It is not as easy as you think! Enjoy relaxing ambient background music while playing the game. Use headphones or earphones for the best experience.
