Tetris Online. Pet Party Columns. Original version of the Tetris game. Blocks with 3 different animal faces will descend from the top. To eliminate them from the game board you must chain 3 or more equal faces forming a horizontal, vertical or diagonal line. Use the ARROW KEYS to move the falling pieces from right to left, alter the position of the faces, accelerate their fall. Each group of animal faces that you manage to eliminate will cause the animal faces above it to move down one position. In this way, space will be freed on the board, which will facilitate the placement of the new pieces that are generated. The rate of falling of the pieces will accelerate as the game progresses. The game of Tetris ends when the pieces are stacked on top of each other to prevent the generation of new ones. Accumulate points by keeping the Tetris game active.
