You can actually download small apps of those titles, and play against the computer.
So you let the computer go first in AC3, and you copy the move in the app, but you then do the computers move in the app to yours in the game.
You will win 100% this way, just make sure to the set the computers skill level on the app as highest.
Do you have any links to these "apps" I have tried a few and the apps that I have found do not have enough pieces to use with Assassins creed 3, there are only 9 pieces and in the AC3's mini game there are like 12 pieces.I know these post are older but I have just started playing, I finally have a rig that can play these games .
