Tetris Online. Hetrik. Original variant of the Tetris game. Blocks of different letters will descend from the top. To remove them from the game board you must chain 3 or more of the same letters forming a horizontal or vertical line. Use the ARROW KEYS to move the falling pieces from right to left, alter the position of the letters, accelerate the fall. Each group of letters that you manage to eliminate will cause the fruits that are above to descend one position and a new upper letter will be generated. 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.
