Conquering new territories is the main priority in the game Expand. io. Your character is a colored cube that you will control. He will start moving from a small colored spot, leaving behind a colored trail. While moving, guide the cube so that its path begins in the colored territory and ends there. Thus, the size of the area will gradually increase. But the color trail should not be interrupted and cross the trail of other characters. At the same time, you can bite off territories from your opponents by sliding over them in Expand. io.
