Tetriz

## Description

_Tetriz_ is a _Tetris_ clone, written in Oberon language with the aims of
being small (6 kB) and running in a window. The game is controlled via the
numerical keypad and comes in three variations: _Tetriz, MegaTetriz_ and
_MiniTetriz_. The plain version has the same width as most _Tetris_ variants,
whereas _MegaTetriz_ runs in a roughly 2 ½ times wider window. _MiniTetriz_ is
only four blocks wide, giving a new dimension to gameplay.

_Tetriz_ was later adapted to run in a text window, under the title of
_Contris_ , which also saw use as a BBS door.
