When you surf (view ads), you can collect sandwiches for the admin. Approximately every 80 pages in surf (it varies a little not to interfere with other prize pages) you will find a prize page where you are asked to collect a sandwich.
For each sandwich you collect by clicking the claim button, you will have 1 ticket in the daily sweepstakes. There is no purchase necessary to enter or win. There are 11 prizes every day:
1 prize of 1000 site advertising credits
10 prizes of 200 site advertising credits.
Winners from the previous day are awarded with the bonus credits automatically, so you won’t have to claim them anywhere. You can see the winners on the “Raffle winners yesterday” page under the Games tab. An alternative way of claiming a ticket in the daily sweepstakes is to send a support ticket with your account details and a food recipe.
