To make it more interesting and suitable for the topic of Dynamic Arrays though, we have added several twists

to the game:

$$ Instead of having the seven predetermined tetrominoes, we play with pieces that have random shapes and sizes

like in Figure $1$ below.

$$ On top of the default moves $($left$/$right and rotate$),$ we also permit flipping $($horizontal and vertical$)$ and scaling

$($up and down$)$ of the pieces.

$$ The board does not have a fixed content throughout the game but certain moves on the pieces can trigger certain

modifications of the board.
