For those with Identity accounts, check your email for a message with the subject "Play Now & Win Guaranteed Prizes for Your Next Visit". It's an offer to win $5-$100 in resort credit by playing a quick free online card matching game. Might be a targeted offer but I got one a couple of weeks ago and I'm a very small fish to them.
Unlike most Casino promos like this where there's a 99% chance you win $5, this one is actually skill based and easy to win more. The credit posted to my Identity account instantly. You don't even have to be staying at Cosmo to use the credit.
The game must be played by May 15th.
