Yes, get PocketConquest (

) by Sean O'Connor. It is his clone of Risk. He also has a clone of Stratego called PocketGeneral (
http://www.handango.com/PlatformProd...roductId=87279), and an original game that I have spent hours and hours playing called PocketSlay (
http://www.handango.com/PlatformProd...roductId=30268).
He has trial versions of each of them so that you can try them out first, and you can get all of them plus PocketRats (not so great a game) here:
