Either the referrals page is incorrect or there is a bug in the game. It gave me 200 moves intead of 100 like it says on the web page.
Just thought I would point that out.
I just double-checked the code and verified that 100 moves are given for each referral. I did notice that you got two referrals today, so that's why you would have recieved 200 moves.
Just a note that referral bonuses will be lowered to 25 moves and 100 Mars Dollars as of tonight. In return, there will be contests with prizes for people who bring in a lot of referrals. Probably something like this:
5 = 100 bonus moves
10 = $5 Amazon gift certificate
20 = $10 Amazon gift certificate
100 = iPod Shuffle
500 = Portable DVD player
I'll post this on the main page later today.
