Abstract: Novel set up racks and games for billiards. The racks set up object balls in arrays wherein the object balls are spaced apart from one another. The arrays are straight, circular, and cruciform. Games played employing the novel arrays may be generally conventional, but add novel steps. One step is that of avoiding touching object balls with the cue ball other than that object ball being projected into a table pocket. Another novel step is that of requiring that the cue ball not cross over a line of object balls. An alternative novel step requires that the cue ball touch opposite sides of the line of object balls on alternate shots. Novel steps employing the circular array include maintaining the cue ball selectively inside or outside the circular array, or alternatively requiring that the cue ball alternate between coming to rest inside and outside the circular array.
