Default Re: is the EV for this game really infinity?

If you are just going to play the game one time, you should expect the game to last two rounds and expect to win $4.

I think your confusion may be because are using a standard English definition of the word 'expect,' and not the precise probability theory definition of the word 'expectation.'

To illustrate: If a friend of mine offered to roll a single dice and pay me $1 if it came up 1-5, but $100 if it came up 6, I would "expect" to win $1, but my "expectation" would be $17.50
