light home

Light

A light version of home screen. Just the basics! Good for being gradually introduced to all the many features found on Backgammon Studio!

In the bottom right quadrant you can scroll through additional sections where each has a description of the section.

chat home

Chat

If you want to watch what is going on at Backgammon Studio you can switch to the chat version of the home screen which will output status updates in the chat when something interesting has happened.

It contains a users list which is updated when someone logs on/off. You can use this to challenge others to a duel/match or to open up a private chat with friends.

There is also a common chat channel you can use.

This is perhaps best for desktop computers with a reasonably large screen.

classic home

Classic

Standard display with a table of contents which shows what is currently going on at Backgammon Studio. A daily surprise position which is surprisingly updated every hour...

The information on this homescreen doesn't update as opposed to the Chat home screen.

This homescreen should work just fine on any device.

compact home

Compact

This can be good for tablets or smaller displays.

Content is organized to better fit a smaller screen.

fancy home

Fancy

A bit more fancy display.

Separate screens you can switch between.

Good for tablets (swipe support).

You can also change this in later.

  • Add 2 for each checker more than 1 on the ace point.
  • Add 1 for each checker more than 1 on the 2 point.
  • Add 1 for each checker more than 3 on the 3 point.
  • Add 1 for each gap on the 4, 5 and 6 point.

Increase the count of the player on roll by one-seventh (rounding down).

  • A player should double if his count exceeds the opponent's count by no more than 4.
  • A player should redouble if his count exceeds the opponent's count by no more than 3.
  • The opponent should take if the doubler's count exceeds the opponent's count by at least 2.

New match notation
Notation is a way to write down matches by entering moves as they are played. This is rather experimental at the moment so don't use it for anything important! It is always better to get a video recording of a match but that option might not always be available.

The basic principle is that you first enter the dice values and then you click on a checker to be moved and then to the target bar. Once done you hit . If you have made a mistake you can hit . If there is no valid move (stuck on bar) you can hit without entering a move. If a bar is full of checkers you can click on a checker there and the checker to be moved will be moved into that stack.

Once a notation is complete it will be submitted to the server and then emailed to your (hopefully valid!) email address.

Backgammon Studio server is moving!
Backgammon Studio will be moved to a bigger/faster server shortly. The process will be done in stages:
  • Private databases are moved. When your private database is moved you will be unable to use it until it has been moved.
    Once moved you will be able to use it on the new server.
  • Main database is moved. You will be unable to log in on the old server when this occurs.
  • Once all databases are moved backgammonstudio.com will point to the new server.
The new server is located at http://45.55.222.217 but using it before all databases have been moved will result in changes being lost.
