This is one game that I think deserves a Do-Over option for when you place a tile in the wrong place. Anyone playing can see how obvious such a mistake was, and in a real board game, you could correct it. Why not allow that here? It would make the games much more playable. I just had to quit a game because I followed a 10 with a 2, thinking the 10 was a 0. Please consider making this game a little more user-friendly. At the very least, there could be a warning.
