Alright, I think I understand the rules now.<p>You earn one "credit" for every dollar you deposit into a registered savings account (or every dollar you pay off a registered mortgage, or whatever).<p>There's no limit to how many credits you can earn, but there is a limit to how many credits you can spend: a maximum of thirty a day.<p>Credits are spent by putting 'em into a big slot machine which dispenses prizes whose value and winning probability are unknown. Hopefully you can get something, though.<p>The best way to game the system seems to be:<p>1. Move, say, $10,000 out of your savings account into your checking account<p>2. Sign up for saveup<p>3. Move the $10,000 back into your checking account, claim your ten thousand credits<p>4. Spin the wheel three times a day for the rest of the year and hope you get enough prizes to make the effort worthwhile.<p>Do I have it right?<p>edit: Aha! I found more information on the precise rules of the contest: <a href="https://www.saveup.com/rules" rel="nofollow">https://www.saveup.com/rules</a> including the probabilities of winning prizes. For instance, your odds of winning the two million dollar prize they're so keen on talking about are 1:170,230,452. On the other hand, your chances of winning $10 are one in 4133. There seem to be various different <i>types</i> of drawing which you can enter, but none of 'em seems to have better than a 1:1000 chance of winning even the most trivial amount of money (five dollars).
