My first round on normal difficulty, you know the one round in which you use the tutorial to get the game, every AI received 2-4 'partners' (without the player getting anything) during the game allowing them to traverse the entire board, sometimes getting two stars per turn. To the developers: "Maybe let the player learn the game before annihilating them, particularly on the lowest difficulty during the initial round." This is not the only issue but marking them all would take to long.
In short, DO NOT BUY THIS GAME, particularly if you are playing with family or friends for the first time.
