I have only hosted two of these, but I didn't realize that it was expected that extra gets returned. I have played several and never got the extra returned. I thought that was part of the risk? Can others comment on if returning extra is standard practice, so I know for future games? I am happy to send it back though since apparently there is some confusion. What is your return address?
I guess if you didn't have enough to pay the next person in line there would be a little left over. I guess you could give what's left to the next person in line, give it to a random person, or divide it up for those you didn't get anything? I'm not sure what the others do though. I don't really do these type of games...
