- COLUMNS - A Tetris-Like Game
- Version 1.01
-
- COLUMNS is a single-player game in which one attempts to manipulate multi-
- colored tiles in order to form sequences of three boxes of the same color
- -- arranged horizontally, vertically, or diagonally.
-
- The COLUMNS game board is a 6 x 18 array of squares. The playing tiles
- drop from the top of the screen, and are comprised of 3 boxes arranged in a
- column -- each box has one of 6 possible colors.
-
- Tiles drop one at a time, and may be manipulated in one of four different
- ways: 1) moving the tile one column to the left (the left command), 2)
- moving the tile one column to the right (right), 3) cycling the colors
- downward within the tile (cycle), and 4) dropping the tile straight down
- into place (drop). You can apply the right, left, and cycle commands as
- often as you wish while the tile is falling.
-
- The game ends when a tile is placed and -- after counting all sequences and
- removing the boxes involved -- a box remains touching the ceiling line at
- the top of the game board.
-
- RUNNING COLUMNS
-
- To run COLUMNS:
-
- COLUMNS [/T] [/G] [/S] [/M] [/C <num>]
-
- /T: Force COLUMNS to run in text mode. This is the default on the CGA
- display
-
- /G: Force COLUMNS to run in graphics mode. This is the default on the
- EGA and VGA displays.
-
- /S: Silent. Beep option is initially off. When on, this option causes
- COLUMNS to beep whenever points are scored.
-
- /M: Monochrome. Only meaningful in graphics mode. Replaces the six
- colors with six different monochrome crosshatch patterns. This is
- the only graphics mode available for COLUMNS on the CGA display.
-
- /C: On COLUMNS startup, cut the Top Ten scores file to contain only the
- top <num> scores per person. For example, if player "jsmith"
- occupies five of the Top Ten spots, "COLUMNS /C 3" will remove his
- two lowest scores from the file. The option does not affect
- administration of the Top Ten file while COLUMNS is running -- only
- what is done at startup time.

- SCORING
-
- The object of the game is to arrange the tiles on the game board such that
- boxes of the same color line up in sequences of three or more boxes. A
- sequence may be formed horizontally, vertically, or diagonally. Points are
- earned when such a sequence is formed: the scoring is a function of the
- number of boxes in the sequence, the current level of difficulty, and, if
- the drop command is used, how far the current tile dropped.
-
- Any time a sequence of three or more boxes is formed, the boxes in the
- sequence are removed from the board, and all boxes located above those
- removed collapse to occupy the vacated squares on the game board. If the
- new arrangement of boxes (after the collapse) forms more sequences, these
- are also removed and points are scored.
-
- DIFFICULTY LEVELS
-
- COLUMNS has ten difficulty levels -- the higher the level, the faster the
- tiles fall. You choose the starting level at the beginning of each game.
- If you start at 0 (the easiest), the level will increase by one for every
- fifty boxes removed. If you start at a higher level, the difficulty will
- remain the same until the appropriate number of boxes has been removed,
- then will start increasing. (For example, if you start at 2, the level
- will stay there until 150 boxes have been removed.)
-
- THE TOP TEN
-
- COLUMNS keeps track of the top ten scores and displays them before each
- game. After a score that qualifies you to enter the top ten, COLUMNS
- prompts for your name. If you play more than one game during a session,
- COLUMNS remembers the name and offers it as the default input on future
- name input prompts. If, when prompted for your name, you press the
- backspace key before any other keys, COLUMNS will erase the default input
- and give you a clear line on which to enter a new name.
-
- The Top Ten record is kept in a plaintext file called COLUMNS.HIS.
