Elegant in it’s scoring mechanism, deep strategy. Fun to play but I’ve never gotten to play a real human. For most, the AI is hard to beat, but over time you will overcome all of them. Dropping a star as 2 player is broken. I suggest adding a Ladder, seed the Ladder order with the present Elo rated players. Challenge anyone within 200 places of you and if you win, you move up 1/2 the distance between you two. If your opponent does not answer the challenge with 3 days, you move up the ladder 1/2 distance, and your opponent moves down 1 place, the same if you win by playing out a game for the Ladder. If the higher player wins, he/she moves up 1 place and the lower ranked player moves down 1 place. Also, Your rating also changes with a Ladder challenge according to Elo difference as it does presently.

This is my favorite game right now. Lots of strategy required, some luck involved, really fun to play due to the often highly non-linear progression of play (a single critical move can have a huge impact on the overall balance of power). I wish there were an undo button to fix errant taps, but otherwise this is just like the (super fun) board game, and relatively quick to play.

A really good implementation of the game with the only snags that keep it from being 5 stars for me is the lack any kind of undo button (a mistaken touch can mean doom) and a log to be able to review what the previous actions of your opponent were. Even with those couple nigglys I highly recommend the app for anyone interested in the game.
