This is a match-three game, which means that you need to switch places of adjacent balls to try and form groups of 3 or more adjacent identical pieces lying on the same line. In this case your playing board is a spider web and instead of having common columns and raws you have circles and radius lines. Some of the balls have letters on them. To pass a level you need to eliminate all balls with letters including them in the same color groups.
