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 tablet displays.

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.

Basic Pip count and add:

  • 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.

Backgammon Studio

Backgammon Studio is an online backgammon database with many features that you can explore. It may be a bit overwhelming at first but don't panic! You don't have to figure out everything in one sitting!

Backgammon Studio tries to be usable on many devices with many different screen sizes. This requires different solutions depending on what device/screen you are using.

There are two important settings you will have to set before you are ready to take on the more interesting features.

Home screen

The home screen or start page can be displayed in many different ways with different amount of information displayed. Some like to get a lot of information while others may like to keep it simple.

The menu

The menu can be displayed in many different ways and you should pick the one which fits your screen best. On mobile devices you should probably always choose the 'dialog' version as it takes up the least amount of screen space. On desktop you have more options.

You can go to settings by clicking the settings button in the top right corner and change these and many other settings later.

If you get lost in the menu system you can always reload the page to get back to the start page.

Help

Most sections will contain a help button which will give you some additional help for the current section.

There is also a forum where you can post any question you may have.

There is an old help section but some information found there might be a bit outdated.

Desktop tips

Finding opponents

A fast way to find opponents to challenge to a match or duel you can click on ctrl-u and then click on another player which will open a duel dialog. Set the desired parameters and off you go!

Site navigation

There are shortcuts for different sections (You can try them out now and this dialog will stay open. Unless this dialog is too big and it will go fullscreen and you won't see anything else.):

ctrl-hHome screenctrl-uUsers list
ctrl-aAnnotated matchesctrl-cClassic challenges
ctrl-mMatches listctrl-iImport matches
ctrl-pPosition forumctrl-qTraining tracks
ctrl-sPlayer statisticsctrl-oPlayer overview
ctrl-vView match errors

Match navigation

You can use the scrollwheel to move forward in the match along with arrow keys.

Mobile tips

Getting more screen space

The most important mobile tip is that you should use the 'Add to home screen' browser option on the device and then launch Backgammon Studio from your home screen.

Playing online matches on mobile

It is possible to play online matches on a mobile but the screen space is limited so there is an option to expand the board.
