We consider variations on the classic video game Tetris where pieces
are k-ominoes instead of the usual tetrominoes
(k = 4), as popularized by the video games ntris and
Pentris. We prove that it is NP-complete to survive or clear a given
initial board with a given sequence of pieces for each
k ≥ 5, complementing the previous NP-completeness result
for k = 4. More surprisingly, we show that board clearing is
NP-complete for k = 3; and if pieces may not be rotated, then
clearing is NP-complete for k = 2 and survival is NP-complete
for k = 3. All of these problems can be solved in polynomial
time for k = 1.
