	    TETRIS for the Atari ST (monochrome only)



DESCRIPTION
	Tetris is a game involving dropping shapes. While a
	shape drops, the player can move it to the left, right,
	and turn it (anti-clockwise). If a shape can't drop any
	further, it will be fixed and a new shape will enter
	the playing field. If the entrance of a new shape is
	blocked the game is over.

	When one or more rows of the playing field are entirely
	filled, they will be removed and higher rows will shift
	downward thus effectively gaining room for more shapes
	to enter the playing field.
	The level will change depending on the number of rows
	the player has removed (level = rows/10 -1).

	Tetris always displays the next shape to come in the small
	window next to the playing field.


SHAPES	The shapes are each build up of four elements (squares).
	For each new shape Tetris will choose randomly out of
	one of these seven shapes:

	**     ****      *      ***     ***     **       **
	**              ***     *         *      **     **


SETTINGS
	Before starting a new game, the player can affect any of
	the following settings (default in brackets):

	Level (0)	Any number between 0-9. The level determines
			the speed by which the shapes drop.
	Advanced (off)	The dropping speed will be multiplied by 2
			for each level.
	Rows (0)	Tetris will randomly occupy the indicated
			number of rows.


PLAYING MODES
	There are three different modes to play Tetris:

	PLAY	Play a normal game of Tetris.
	HELP	For each new shape Tetris will give his best guess
		where to place it.
	ROBOT	Tetris will play the game himself.

	In the latter two cases the high score will not be effected.


KEY BINDINGS
	<Left  arrow>		Move the shape left (also h key)
	<Right arrow>		Move the shape right (also l key)
	<Up    arrow>		Turn the shape (also k key)
	<Help>			Drop the shape
	<1-9>			Change the current level (upward only)
	<Space bar>		Pause the game
	<Esc>			Quit the current game


SCORE	The player gets points for every shape positioned on the
	playing field. The number of points depend on the current
	level, and the height where the shape is positioned.
	Extra points can be obtained by dropping the shape (HELP key)
	or playing in advanced mode (see SETTINGS).


BUGS	The ROBOT mode doesn't consider the next shape in his choice
	for the most efficient position of the current shape.
	The robot plays quit well however (I measured an average of
	12500 points over 40 games, with a maximum of 42598!).
