Donohoe Digital released DD Poker 1.0 in June 2004 and it quickly went on to become the #1 selling poker software in the world, with over 150,000 copies sold. DD Poker 2 arrived in Fall 2005 with major new features such as online play and a sophisticated odds calculator. Improvements were made consistently over a dozen point releases culminating with the release of DD Poker 2.5 in Summer 2006.  The final release DD Poker 3 was made available for free before the closure of Donohoe Digital in 2015.
