I wanted to check this out but I cant find it, is it already ended? As you call it as daily wager contest, it should be available every day unless you decided to stop it after the first day because of a specific reason (probably less interests from players). If it is true that you have stopped it, I'm starting to think that you always want to have instant result (good traffic) from every promo you tried. I know it is hard to gain good traffic of real players due to the huge competition among online casinos but if you cant offer something more regular, I doubt you can build your own traffic. Dont take it as an offensive feedback but take it as a motivational feedback to make your site  better.
