Garbage Puyo block the opponents' playing fields, and can cause them to lose if one is placed the third spot from the left in the top row. Garbage Puyo are cached above the opponent's playing field, and do not fall until the attacker's chain concludes, and then the defender puts down a piece. If multiple groups of Puyo are cleared in succession due to a chain, the amount of Garbage Puyo will increase based solely on the number of steps in the chain. Garbage Puyo are translucent pieces that disappear when Puyo are popped next to them. When a Chain is achieved, Garbage Puyo, or Ojama Puyo (гЃЉй‚Єй”гЃ·г‚€, hindrance Puyo) are sent to either clog the opponent's screen or to cancel out (offset, з›ёж®є) the Garbage Puyo sent by the opponent. ДЄ Chain is made when falling Puyo cause a new group of Puyo to Pop, making a chain reaction. Simultaneous Pops (еђЊж™‚ж¶€гЃ—, simultaneous erasing) are created when more than one group is formed at a time. The Puyo above those that are cleared fall onto other pieces or the bottom of the screen. Puyo of the same color can connect horizontally or vertically, but not diagonally. When four or more Puyo of the same color line up adjacent to each other, the Puyo will connect to each other, 'Pop', and disappear. The piece falls until it reaches another Puyo or the bottom of the screen. The pieces can be moved, dropped, and rotated as they fall. Puyo are round, slime-like creatures that, in most variations of the game, fall from the top of the screen in groups of two, three, and four. Generally, the objective of Puyo Puyo games is to defeat your opponent by causing the third column from the left of their side of the screen to become filled with Puyo.
