The objective is to change the coloured squares in the 6 x 6 board. Roll 4 or more marbles of the same colour next to each other to remove them. The squares under the disappearing marbles will change colour. A board is solved when all its squares become grey, then you can move on to the next board. The game contains 30 levels.
