The update to Backgammon 2.5 adds the application to the RiP Dev source. In doing so, the full version of the game is no longer available via a donation. The game now costs $9.00 USD. It does however come with a free 3 day trial. There are not any huge new features or visual changes to the application so, the main reason for the update is that you now have to purchase the full version of the application. However, if you have donated in the past for this application, you will receive an activation code in your email (without having to pay the $9.00). If you have not received your activation code and you have previously donated to Backgammon, you can email proof of payment to firstname.lastname@example.org. Backgammon is available through the RiP Dev source.
