It's a good game with great mechanics but would be better if the UI wasn't designed to make you click affiliate links. Even if you buy the full version, you still have to watch ads or buy undos once you run out of the initial 100...if you buy the FULL game, you'd expect to get the FULL features of the game. the latest uodate also doesnt allow you to try the daily board twice, only once (this seems to be fixed although thr black bar at the bottom is blank and doesnt say press here to try again).
