Love this game – Philosopher's stone 4096 with undo, remove and replace. Review

Would love even more if you could save your game!! This is one of my favorites - very relaxing and still challenging. The graphics are great and now you can undo moves. The only thing is that it's a little frustrating that the game starts over by itself when you open it back up, instead of picking up where you left it.
