<Li> The outer edges of the triangle must be in the pattern of solid, stripe, solid, stripe, etc. (resulting in the two corner balls being either both stripes or both solids). </Li> <Li> Sometimes, the balls must be placed in numeric order from the top of the triangle down and from left to right, i.e., the 1 on the foot spot, followed by the 2 then 3 in the second row, and so on . This always results in the corner balls of the rack being both stripes (the 11 and 15, respectively). </Li> <P> In nine - ball, the basic principles are the same as detailed in the eight - ball section above, but only balls 1 through 9 are used; the 1 ball is always placed at the rack's apex (because in nine - ball every legal shot, including the break, must strike the lowest numbered ball first) over the table's foot spot, and the 9 ball is placed in the center of the rack . </P> <P> Some players (most often amateurs) place the balls in numeric order but for the 9 ball; from the top of the triangle down and from left to right, i.e., the 1 on the foot spot, followed by the 2 then 3 in the second row, and so on . However, all balls other than the 1 and 9 may be randomly placed . Note that racking in numeric order in nine - ball, unlike in eight - ball, does not result in a contravention of the official rules . </P>
