The main objective is to clear strings of rolling marbles, by matching those with same colour. Shoot toward the marbles with same colour and they will be cleared from the play field. This clearing creates gaps through which a player may shoot more marbles at nearby stDragon Tiger Rummyrings, target bonus coin etc. Gaps automatically close if the balls at either end of the gap are (or become) the same colour, potentially creating chain reaction matching and clearing as new sets of three or more are formed.
