Each turn in Marbleous, you choose a marble card on display, then roll those two or three marbles into your grid. If three or more marbles of the same color are touching, they pop, with you grabbing the scoring card matching the color and size of the group — and if you form another group after removing those marbles from the grid, those pop, too.
Make large groups, and you earn bonus markers that allow you to drop a marble of its matching color into your grid, giving you a better chance of scoring a large group.
In the advanced game, you earn a star whenever you pop two or more groups on a turn, allowing you more choice over the scoring card you grab, in addition to earning extra points at game's end for the stars you've collected.
