The AIs smartness grows from level to level. I know there is a very big advance from level 3 to 4 but thats the way the AI works. The Zune will try to "look xx steps forward". Try looking forward 4 steps yourself and you might win *lol*
There still is a chance to win! I always let the player the first move and researches have proofed that the beginning player can always win, no matter of the strategy of the second player.
I will take a look if I do something like:
Level 4:
First move (look 3 steps in the future)
Second move (look 4 steps in the future)
Third move (look 2 steps in the future)
etc...
this should make a mid hard level... I will test it out.
