Well as expected, the expectimax(by depth search), cannot take you further, only way is machine learning; On the most recent set of tests, it reaches (4096) 99.4% of the time, gets the (8192) tile with a 91.8% success rate, and reaches (16384) in 34.6% of its games. I mentioned that in the AI code… In later time, in my free time, I will try to rise the success rare for the (16348)

Thanks for the feedback, this was fun to code, I always makes collections of things.
