re: I cannot figure out the logic of this.

You could look at it as kind of a payroll deduction plan. They'll blow that $100 weekly on insconsequential bullshite, or they can net $900 every ten weeks and have a hellacious blowout.

Also, the guy who wins the first time is always ahead. The worst he can do is break even. When he quits or the game ends, he'll be anywhere from $0 to $900 up, depending on where he is in the cycle. Everybody else is always playing catch up.
