It's interesting that in class we determined that the best strategy is tit-for-tat but when playing this version at home, that never worked for me. I seemed to get the best score by cheating every time and even then my score was not that much better because the computer seems to use the tit-for-tat strategy. I would like to comply every time and cheat at the end but I never know when it will end. The computer always tells me that I could do better so I must be missing out on some brilliant strategy! If anyone can beat this game significantly, let me know how you did it!
