PYRAMID
The cue ball (red ball) is used for hitting. A random player starts by breaking a pyramid of balls. The balls scored in the pockets are counted to the current player, except for penalty situations: if the cue ball falls into the pocket, then the balls scored on the current move are counted to the opponent; if the balls fly out of the playing field not through the pockets, then they are counted to the opponent. If a player does not score a ball or a penalty situation occurs, then the right of the move passes to the opponent. If the cue ball is lost, it is randomly placed in an empty place in the home zone. The first player to score eight balls wins.
KILLER
At the beginning of the game, each player has five points (lives). The players take turns. The cue ball (red ball) is used for hitting. A random player starts by breaking a pyramid of balls. If a player does not score a ball into the pocket or a penalty situation occurs (the cue ball falls into the pocket or the balls fly out of the playing field not through the pockets), then one point (one life) is taken away from him. If the cue ball is lost, it is randomly placed in an empty place in the home zone. If there is one cue ball left on the playing field, then a new pyramid of balls is built. The player who loses points to zero loses, the survivor wins.
