1. Introduction

Backgammon is a game of luck and skill. It is the oldest board game recorded in human history, most probably dating back to the Persian Empire some 5000 years ago. The ancient Greeks as well as the Romans played it. The game we know today was refined in England in the seventeenth century, which is also when it acquired it's name, Backgammon.

The rules of backgammon are simple and easy to learn. In fact, it is quite remarkable that a game as rich and interesting as backgammon has such a simple set of rules. The description of those rules is outside of the scope of this document, but you can check out many Internet sites on the subject, they are of high quality and explain also basic strategies. Try Backgammon Galore or Salar's Backgammon page.

7. FAQ

• OK, how do I start playing?
  When you start up Backgammon v2.2, you should be presented with the board, 30 tokens, and two dices. If you want to play the right dice first, just tap on one of the dices, they will switch position immediately. Tap the token that you want to play; if this move is valid the token will move by the number of spaces indicated on the left dice. When you have moved a token for both dices, tap on the "Done" button to indicate that you are finished.
  Than, the computer will play. You must tap again the "Done" button to acknowledge its move.
  Now it's your turn again!



• How can I undo a move?
  Before pressing the "Done" button to validate your move, choose "Undo" on the menu bar. This will bring you back to the initial position. You can move again



• I would like to play the right dice first!
  You can switch the two dices' position, just click with your pen on any of the two dices. That's it.



• I didn't see my opponent's move. How can I be sure it was valid?
  Before tapping the "Done" button to acknowledge your opponent's move, chose "Undo" on the menu bar. The initial position will show up for 2 seconds.



• What is the Disable "Done" tapping option (in the Preferences)?
  Obviously, it's annoying to tap on the "Done" button to validate your moves and acknowledge those of your opponent. If you check this option, the next turn begins without any validation or acknowledgement. This makes the game more fluid.
  The drawback of this option however is that you won't be able to undo your second move because the opponent's turn begins right away. You won't be able to check your opponent's move either, because your turn begins immediately after his ends. The doubling cube (when implemented) won't be available in this mode either.



• How can I make the Palm play against itself?
  In the preferences screen, select "Computer" for both black and white player.



• I installed Backgammon v2.2 on top of v2.0, but nothing happened.
  This is because you didn't remove version v2.0 before installing the latest update. Remove now completely Backgammon using your luncher (menu App / Delete). Reinstall Backgammon v2.2.



• Can you make an Acey-Deucey game also?
  Several people asked me to make such a game. I'm considering it, but the rules seem to be a little bit different, and probably the Palm should also play differently (Rework of the Artificial Intelligence). Other enhancements have higher priority for now, especially the doubling cube.



• Where can I download the latest version of Backgammon?
  You can download Backgammon on several Palm related sites, but for the very latest version try this link.
  You can also write a review for Backgammon.



• How come such a nice software is free?
  I made this game in my spare time, mainly for entertaining myself. I never intended to make money out of it, I'm not sure you can make money with sharewares anyway. Backgammon is freeware and all future versions will still be free!!!!
  If you like this software however, send me an e-mail (schall@bigfoot.com) to tell me so. This is the unique reward I expect from You. My statistics are not very promising for now: last month I had 20,000 downloads and only 30 e-mails, that means an answer rate of less than 0.2%. You can help to change these figures!
  Remember, any comment is welcome! Bug descriptions, suggestions, encouragements, all of these help me to deliver a better software.
  Thank you for playing Backgammon v2.2, enjoy!
