Frozen Bubble is an amusing little game with sharp graphics, nice music, and easy game play. You may play alone or against another player. The goal is to use your colored marbles to knock down the ones above you within a certain amount of time. You have to hit at least two at a time that are the same color as the one you shoot for anything to fall; otherwise, your shot joins the menagerie above and brings your demise somewhat more quickly, as illustrated in Figure 7.5. There is a lot more to Frozen Bubble, but even with the details it is easy enough for a child to play and interesting enough to hold the interest of most adults.
