SIRTET

## Description

_SIRTET_ is a variant of _Tetris_. The object is to fill complete horizontal
lines with the pieces that drop from the top of the screen by rotating the
pieces and dropping them on the playing field. _SIRTET_ differs from _Tetris_
in that it does not offer the standard set of seven tetrominoes. Instead, the
player select which of nine different pieces can drop. Additionally, the play
may configure several other options, including the speed with which pieces
drop and the size of the playing field.

The player scores by dropping a piece before it reaches the bottom. _SIRTET_
keeps a ‘hall of fame’ recording the 20 highest scores.
