The game itself is okay (annoying that it holds your hand through the tutorial and doesn't even ask whether or not you have played before or want to skip ahead). But the app crashes *constantly*. I had to replay several games during the tutorial because it crashed upon me winning. This isn't isolated at all - it happens very frequently. In fact it literally happened to me just now, prompting me to write this review. Love the game, can't recommend until it becomes faster/more stable.
