There is a ticket drawing every day in Hungry For Hits. You collect tickets by viewing ads, surfing. 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 draw. 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.
