There's a weird bug where you can only get one medal per play (specifically the lowest one available) so if you play the first time and get 800 points you'll get the 200 point medal. If you play again and get 800 points you'll get the 600 medal. Then finally the third time you'll get the 800 point medal. This needs to be fixed, particularly given that the medals are secret and the fact that this is happening is not obvious to the player.
