Seems the guys over at BrailleSoft have released a selection of games for both pocket PC and smartphones, though the Pocket PC ones are designed for the Pac Mate so I can't vouch for how they work on other systems. The smartphone ones also seem likely to be for Windows mobile Smartphone edition, the page doesn't specify so I've shot off an email suggesting a clarification.
The games include such things as Uno, Battleships and Blackjack. Though you may have to install the "compact" version of the .net framework, there are instructions and all necessary links on the appropriate pages. And remember to do a soft reset, which is equivalent to rebooting a Pocket PC so that it can take hold properly once the framework is installed.
