5 in 1 Tetris

Five different versions of Tetris in one game. The player's task is to arrange the blocks so as to form a minimum of one full line horizontally. Each such line disappears making room for another. As you progress, the level of difficulty increases by speeding up the falling of the blocks. The first version offers a game of classic Tetris, the second involves filling in gaps in a falling wall, the third is Tetris with blocks of five elements, the fourth is a snake that increases in length after eating a block and the fifth is mixed Tetris with blocks of five segments.
