The Cosmopolitan of Las Vegas has one of the best slow play promotions on the Las Vegas Strip.  From now until January 31, 2014(but probably will be extended indefinitely), if you end up losing up to a $100, you will be reimbursed with up to $100 worth of free slot play.  Basically, if you sign up with their identity membership and participate in this promo, the Cosmopolitan will cover up to $100 of your losses by reimbursing it with free play.  This is a one day thing only, and definitely worth doing, even for a non-gambler, since this will increase your chance to win significantly.  You must have an overall loss to actually be able to redeem this promotion though.  What I mean is if you are up $100 on day 1, and then on day 2 lose $100, you still haven’t lost anything according to the Cosmopolitan and won’t be reimbursed the $100 in free slot play.

Lose $100 in a Day & It’s On Us. Now Through January 31, 2014.

Play your favorites slots in our casino, and if you lose $100 in a day, we will reimburse you with $100 in Identity Play. Just bring your card to the Identity Membership Desk after your loss to receive your $100 in Identity Play. Players can receive $100 reimbursement one time only and the slot loss must be greater than or equal to $100 on that calendar date. Cannot be combined with any other offer. Available to new Identity enrollments only. Offer only redeemable once. Visit the Identity Membership Desk for more info.
