undefined post name
this is supposed to be a number game...
apparently it sucks
if you still want to play the options available are coin, dice, cups and classic (view code if you want more details)
if you decide to quit, type no or anything that has the meaning of no
The post name could use a little more work. Also, you might wanna skip the rest of the program if the user gives an invalid input, it takes me into the game even if I don't type a valid game type. Also, you may also want to display the available game types, I had to go through your code to figure them out.
