This game is a joke. Tiers 1-4 are fairly simple. The final tier (granny) is fixed. Its like she can see your hand. Strategy is out the window. Ive beat her about 3-4 times but the only way to do it is to cut her and that means dumping possible runs etc. Plus it is amazing how many times she discards a card you needed immediately after a discard (after u broke a run, etc.). Dont buy this game.
