is running a promotion where they will rebate 1% of all your blackjack action. The bonus will be paid out on Thursday and must be used by Sunday. You must wager the bonus through 3 times before withdrawing. Although the rules specify that the wagerthrough must be in the sportsbook, I have been assured that 3x wagerthrough in the casino is fine as well. A minimum of $5 rebate must be earned to be eligible. They don't specify a maximum, but I would ask first if you plan to hit this hard.
Rebating 1% on this game makes it a positive EV play.
