2	Basic Rules of Backgammon 
This chapter provides a brief introduction to the rules of backgammon. If you 
are an experienced player, feel free to skip this Chapter entirely and go on 
to Chapter 3, which discusses the details of Backgammon for PalmOS. This 
chapter makes no attempt to go into the intricacies of backgammon strategy, 
and any readers that are interested should take a look at any of the many 
books that have been published on the subject.

2.1	BackgammonÕs Objective 
The objective of backgammon is to move all of your men to your home board, 
and then off. The first player to do so wins the game.

2.2	The Board 
The backgammon board is made up of 24 triangle-shaped spaced called points. 
Each player has 15 men that move around the board on these points. Backgammon 
for the PalmOS sets up the board for you, so you donÕt need to worry about 
that.

2.2.1	Bar 
The space in the middle of the board is called the Bar. Any pieces that are 
bumped are placed on the Bar until they can enter play again. For information 
of bumping pieces, please see Section 2.5.

2.2.2	Home Boards and Outer Boards 
Each Player has a Home board and an Outer board. In Backgammon for the 
PalmOS, the upper left hand board is WhiteÕs Home board, and the upper right 
hand board is WhiteÕs Outer board. The lower left hand board is BlackÕs Home 
board, and the lower right hand corner is BlackÕs Outer board.

2.2.3	Direction of Movement 
WhiteÕs pieces move from BlackÕs home board to WhiteÕs home board. BlackÕs 
pieces move in the opposite direction: from WhiteÕs home board to BlackÕs 
home board.

2.3	Deciding the First Move 
To decide the first move, both players roll one die. The player with the 
higher roll moves first, using the die values that were rolled to decide the 
first move. If both players roll the same number, the dice are rerolled until 
one player rolls a higher number.

2.4	Dice Rolls and Movement 
Each playerÕs turn starts with them rolling two dice. The numbers that are 
rolled on the dice determine how far a player can move a man on the board. 
For example, if a 4 and a 6 are rolled, you could move one piece four spaces 
and a second one six spaces; or could choose to move one piece six spaces and 
then the same one again four more spaces, for a total of ten spaces.

The exception to this rule is when a player rolls doubles. When doubles are
rolled, the player gets four moves of the double rolled, rather than just two.
For example, if you roll 3,3 then you could move four pieces three spaces
each, one piece three spaces four times for a total of twelve spaces, or some
combination in-between. Sometimes, you cannot move one or more of your die
rolls. In this case, you make the moves that you can, and lose the rest. If
you have no legal moves, then your turn ends.


2.5	Blocked Points 
If a point has two or more pieces on it, then it is owned by the player whose 
pieces are there. None of the opposing playerÕs pieces can be moved to that 
point. If one player blocked six points in a row, the group is called a 
Prime, and no enemy pieces can get past it.

2.6	Blots and Bumping Pieces 
If there is only one piece on a point, then is called a Blot. Blots are 
vulnerable, and should be avoided if possible. If your opponent lands a piece 
on one of your blots, then your piece is bumped, and moved to the Bar.

2.7	Getting Bumped Men Back Into Play 
If one or more of your men are bumped to the Bar, then you have to bring 
these men back into play before you can make any other move. Bumped men start 
at the Bar, and are brought back into play on the opposing sideÕs Home board. 
If you cannot bring a bumped piece into play because of blocked points, then 
you lose your turn.

2.8	Bearing Off 
The ultimate goal in backgammon is to bear off all of your pieces. Bearing 
off is the process of moving a piece of yours off the board from your Home 
board. Most importantly, you may only bear off pieces if all of your pieces 
are in your home board. Once all of your pieces are in your home board, any 
roll that moves a piece off the board will bear it off. If you bear all of 
your pieces off the board, then you win the game.

There are also a few special rules involved with bearing pieces off. If you
have a die roll that will let you move pieces within your Home board, you are
not required to bear a piece off. Also, if you have a die roll that is greater
than the number needed to move a piece off, you can use it to bear the piece
off. However, you must use the roll on a piece furthest away in the home
board. For example, say you have a piece on the three point, and the five
point, and you roll a six. You are allowed to use the roll to bear off the man
on the five point, but not the three. Continuing the example, say that next
turn you only have a man on the three point and you roll another six. Now,
because the man at the three point is the one furthest out in the Home board,
you can use the six to bear the piece off.

2.9	Scoring and the Doubling Cube 
A win in backgammon is usually worth one point. However, there are several 
things that can change that. If you bear all of your men off of the board 
before your opponent gets any off, then you have achieved a Gammon, which is 
worth two points. If you bear off all of your men and your opponent has a man 
on the Bar or in your home board, then you have achieved a Backgammon, worth 
three points.

The game is made more interesting with the use of the doubling cube. The
doubling cube has numbers 2, 4, 8, 16, 32, and 64. At the beginning of the
game it starts at 64, showing that neither player has doubled. At any point in
the game, either player can choose to double by placing the die on the board
with the 2 facing up. The game is then worth twice the points that it normally
would be worth. The doubling cube is now kept by the player who was just
doubled. This way, one player cannot keep raising the score. Each player
always has the choice of refusing a double. However, if you refuse the double,
then you lose the game at the point value before the double was offered.

3	Backgammon for PalmOS 
Chapter 2 described the rules for any backgammon game, and this chapter 
explains the specifics of playing backgammon on your Pilot.

3.1	Starting a New Game 
To begin a new game of backgammon, tap on the Menu button and select Options. 
From the Options menu, tap New Game. This returns the board to the starting 
position and begins a new game. You can also use the shortcut Command-N to 
begin a new game as well.

3.2	Making the First Move 
To start a game of Backgammon for the PalmOS, tap the Roll Dice button. This 
makes the roll that decides who goes first. The die on the left is for White, 
and the die on the right is for Black.

3.3	Rolling Dice 
To roll the dice, tap the Roll Dice Button. You begin each turn by rolling 
the dice.

3.4	Moving Pieces 
Pieces are moved in one of two ways. The first way is to tap and hold on the 
piece you wish to move, and then drag it to the destination point. The second 
way is to tap the piece you wish to move, and then tap the destination. If 
you are in a position where you cannot make a move, tap the Roll Dice button 
to end your turn. Backgammon for the PalmOS will not let you end your turn if 
your still have any valid moves left.

3.5	Bearing Pieces Off 
To bear a piece off, tap on the piece and drag it off of the board. All the 
standard rules apply when bearing pieces off, so you must have all of your 
men in your home board before you can bear any of them off.

3.6	Bringing Bumped Pieces Back Into Play 
If you have a piece that has been bumped to the Bar, you need to bring it 
back into play before you can make any other move. To bring a bumped piece 
back into play, tap on the destination point for the man. It will then be 
moved there automatically.

3.7	The Doubling Cube 
In Backgammon for the PalmOS, the doubling cube starts at one. To double the 
other player, tap the doubling cube. If you are doubled, then you have the 
option to accept or decline the double. If the double is declined, then the 
declining player loses the game. The only time that you can double is before 
you roll the dice for your turn.

WARNING: If you have Auto-Advance Turns set on, then you will not be able to
double.

3.8	Taking a Move Back 
To take a move back, tap on the Menu button, andselect Edit. Then, tap on 
Undo Move. Alternatively, you can use the short cut Command-U. You can only 
use Undo Move to take back one move.

4	Statistics and Preferences 
Backgammon for the PalmOS has a number of ways to customize the game to your 
preferences, as well as keep track of the statistics for your games. All of 
the options listed below can be found by tapping the Menu button, and then 
selecting the Options menu.

4.1	Settings 
The Settings screen lets you customize the game to your preferences.

4.1.1	Computer Opponent 
If this box is checked off, the computer takes one of the sides in the game. 
If it is unchecked, then both sides are human controlled.

4.1.2	Computer Plays White or Black 
You set the side that the computer plays by tapping on either the White or 
Black box. The color selected is the one played by the computer.

4.1.3	Computer Skill Level 
The computer player has four different skill levels: Beginner, Medium, Hard, 
and Expert. The selected box determines the level of the computer. In the 
Beginner and Medium levels, the doubling cube is disabled.

4.1.4	Auto Advance Turns 
If this box is checked, the dice are automatically rolled as soon as the turn 
begins. This speeds up the game, but because the doubling cube needs to be 
used before the dice are rolled, you can never double if this option is 
turned on.

4.2	Dice Statistics 
The Dice Statistics screen shows you the number of times each combination of 
dice has been rolled. The number to the left of the slash is for White, the 
number after the slash is for Black.

If you tap the Show % button, then the screen shows you the percentage of
times that the dice combinations are rolled for each player. If you tap the
Menu button while at this screen, the Option menu appears with the choice to
reset the dice statistics.

If you tap the Menu button while at this screen, the Option menu appears with 
the choice to reset the game statistics.
