Nice game if you want to learn the game against an AI.
Once you get the hang of it you'll quickly start winning, always, including the hardest level. What spoiled it for me though is that in hardest level whenever the AI draws a face down card it always draws the card it needed most. Very annoying that each time there is an island with 2 connections occupied by the AI and 2 by yourself and then the AI decides to draw a face down card it always draws the deciding card, without exception, always. So now I play this anticipating that draw as well.
