Backgammon Roll Recall

Play matches against GNU Backgammon (further on only referred to as GNU), analyze your matches, extract your mistakes and learn from them. You’ll face these critical moments repeatedly until you master them, ensuring you never make the same mistake again.

Before you start Adjust the GNU Settings.

The basic process is as follows:

Play a Match in GNU

Click on New and select the options according to your match preferences. For tips and tricks how to play against GNU read the GNU User Manual.

Analyze the Match with GNU

In the menu go to Analyze - Analyze Match or Session. It'll take a minute or two until GNU did it's calculations.

Export the Match from GNU

After the match has been analyzed click on Save. You can leave the default name as it is but select HTML as file format.

Extract Blunders in BG Roll Recall

Click the Extract button and select all the analysis files from which you want to extract the blunders. Multiple files can be selected at once. BG Roll Recall extracts the blunders only once.
