The best versions of Tetris are random in sets of 7. There's a "bag" of all 7 shapes and the next piece is picked from that bag until the bag is empty and then it refills.
20 cycles through the bag can be packed into exactly 56 lines and that pattern can be repeated forever. Such a solved game might not meet everyone's definition of best. Although for casual play it's great to have every piece coming regularly.
