- ProGammon v2.3
-
-
- This program plays a very strong game of backgammon. It was written
- using SAS/C version 6.58 and is designed to run on any Amiga with OS 2.04
- or higher. It's NTSC but will use an AGA (640 x 480) Multiscan screen if
- available.
-
-
- THE BASICS:
-
-
- The game begins with the following board setup:

- Your HOME area is positions 1 to 6.
-
-
-
- There are 24 positions on the board and each player begins with 15
- stones. 'X' represents your stones and the 'O' represents the Amiga's
- stones. In the diagram above you have 2 stones on position 24, 3 stones
- on position 8 and 5 stones each on positions 6 and 13. The 3 and the 5
- in the center of the board represent the dice.
-
- Each player takes turns rolling the dice and moving their stones an
- amount equal to whatever was rolled.
-
- The object of the game is to move your stones in a clockwise direction
- into your home area. When all 15 stones are home you can remove them
- from the board depending on what you roll. The first player who removes
- all of their stones from the board wins the game.
-
- The game starts with each player rolling one die to determine which
- player gets to go first. For example, if the Amiga rolled a 3 and you
- rolled a 5 then you would start by using this combination for your first
- move. Here is one possibility:

-
-
- With the 3 I moved one stone from position 24 to position 21. For the
- second move I moved a stone from position 13 to position 8. After the
- opening move each player alternates rolling the dice.
-
- Either player can move to any position as long as it is not blocked by
- 2 or more of the opposing players stones. In the above example I would
- not have been allowed to use the 5 to move a stone from position 24 to
- position 19 because the Amiga has position 19 blocked.
-
- It is possible to move to a position that has only 1 Amiga stone on
- it. When this happens, your stone will take possesion of that point and
- the Amiga stone will be knocked off onto the center bar. Any stone on
- the bar has to enter the board in the opposing players home area. You
- must get back on the board, on a point that is not blocked, before any
- further moves are allowed. If you cannot make a move just click once on
- the dice to give up your turn and resume play.
-
- When all of your stones are home, you can start removing them from the
- board. This is called bearing off. If, for example, you rolled a 6 and
- a 2, you could remove one stone from position 6 and another one from
- position 2. If you rolled a 6 but didn't have any stones on position 6
- to remove then you are allowed to take one stone off the next highest
- position. It is also legal to move stones within your home area rather
- than bearing them off. It might be an advantage to do this if the Amiga
- still has some stones in your home area and is trying to knock you off
- onto the bar.
-
- The only other rule is that both players must use as much of what they
- rolled as possible. If you rolled a 5 and a 3 and it is possible to use
- both the 5 and the 3 then you must make both moves. If you can only use
- the 5 or the 3 but not both then you are required to use the higher
- amount(5). The Amiga plays by these rules and now, in version 2.3, you
- are forced to play by these rules also.
-
-
- GAME PLAY:
-
- To move a stone just click once on the stone and then once on the spot
- where you want it to go. If you did it right then the stone should move
- to the new location or else a message will appear to help you out.
-
- If you roll doubles ( i.e. two 3's ) then instead of getting two moves
- of 3 you get four moves of 3. Anytime during a move you can get an
- update to how many moves you have left by clicking anywhere outside the
- main board area. In the message area will be displayed the dice values
- that have not yet been used.
-
- You can also make multiple moves. If, for example, you roll a 3 and
- a 4 then you are allowed to make one move of 7 as long as both points
- between your present location and your destination are not blocked.
-
- If you are unable to make a move then just click once on the dice to
- continue with the game. If you select a stone by mistake then just click
- on that same stone to start your move over again.
-
- Once all your stones are in your home area, you can remove them from
- the board by double clicking on them.
-
- A gammon will be declared if one player is able to get all his stones
- off before the other player has removed one. This is equivalent to
- winning 2 games. A backgammon occurs when one player gammons the other
- player plus he traps at least one of the opposing players stones in his
- home area. This is worth 3 wins.
-
-
- MENUS:
-
- By selecting Colors from the main menu you will be able to adjust
- both the board colors as well as the speed of the game.
-
- If you select SAVE in the color adjustment window then your game
- preferences will be saved to a 266 byte file called gammon.prefs in the
- current directory. The program keeps track of the AMIGA's winning
- percentage in this file as well as statistics on the dice. If you want
- this feature then remember to click on SAVE before the end of the first
- game. Your old version 2.1 gammon.prefs file will automatically be
- upgraded to this new version while maintaining your color selections and
- your win - loss record.
-
- There is also a version in which all 15 stones start off on the
- center bar and you have to get all the stones back on the board before
- you can start to move them. Just select BAR in the menus and then
- select New Game to play this version.
-
- Selecting Stats in the menus will display a table of what you have
- rolled so far as well as what your average roll has been. A long term
- average roll of 8.167 is ideal. Clicking on the left side of the stats
- window will show the statistics for the present series of games and if
- you click on the right side the long term statistics in the gammon.prefs
- file will be displayed.
-
-
- TOOL TYPES:
-
- MAINFONT=topaz
- FONTSIZE=11
-
- These 2 tool types allow you to use any reasonably sized font for your
- menus, message display and window title in VGA mode. If the program is
- unable to find this font or if your size choice is too large then it will
- use topaz 8 as the default.
-
-
- REVERSE
-
- I prefer setting up the board so that you move your stones from the
- upper left part of the screen to the lower left in a clockwise direction.
- If you would prefer that the board was set up so that your stones move
- from the upper right part of the board to the lower right in a counter-
- clockwise direction then use this tool type.
-
-
- NTSC
-
- This tool will force the program to use a 640x200 NTSC screen or dblNTSC
- screen if available.

- MAILWARE:
-
- You will be hard pressed to find a significantly better playing
- computer backgammon game on any platform at any price. Questions,
- comments and bug reports are most welcome. Users who register will
- receive a keyfile that unlocks some additional features.
- Long live the AMIGA!
