just in front of the . The most common varieties are the following, each of which has slight local variations on the rules: Free pyramid (also known as American pyramid) Any ball may be used as the cue ball. Players can pocket the ball they struck if it hits another ball first, with the goal being to the struck ball off of one or more other balls into a pocket. Should the struck ball be pocketed without striking any other balls, the shot is a and that ball is behind the baulk line. Dynamic pyramid (also known as Siberian pyramid or Nevsky pyramid) Only one ball is the cue ball. Players can pocket the cue ball with a carom shot off another ball and then the scorer must choose an object ball to be taken off the table. The player then has and may place it anywhere on the table but may not pocket it until the next stroke, otherwise it is a foul. Combined pyramid (also known as Moscow pyramid or combo pyramid) Rules are the same as in dynamic pyramid, except that, after the cue ball is pocketed, the cue ball is spotted between the () and head/baulk, but not on top of that line; from here until the next stroke, balls can be only pocketed in the side and far-corner pockets. In pool, this part of the table is called the and the Russian equivalent is (dom), 'house'. Classical pyramid Rules are similar to fifteen-ball pool. The object is to score at least 71 points. For each correctly pocketed object ball, the player wins the number of points on the ball (except for 1-ball, which scores 11 points). The last remaining ball on the table, regardless of its number, is worth 10 points. The total number of points is 130. 14.1 pyramid (also known as straight pyramid or long pyramid) Rules are very similar to free pyramid except it continues after potting eight balls until 14 balls are pocketed, similar to straight pool, which 14 balls are respotted into an incomplete pyramid. The objective is to score at least a given number of points. Scratch pyramid (also known as SVOI) Similar to free pyramid, but pocketing object balls before the cue ball is a foul, therefore the player must pocket the cue ball after hitting object balls, which in this case, other balls can be pocketed as
