Total Rewards has added a new level to its Bonus Tier Credits for certain levels of action. If you earn 5000 Tier Credits in a single day, you will get 10,000 Bonus Tier Credits. That will give you the 15,000 Tier Credits you need to achieve Diamond status in a single day. Earning 5000 Tier Credits in a single day is no small feat. It requires $25,000 through slot machines or $50,000 through a typical video poker machine.
Unlike the old version of Diamond in a Day which only gave you Diamond status for the rest of the year, the new system gives you full Diamond status which is good for the rest of the current year, all of the next year and until the end of March the following year. Getting Diamond in a Day today (January 2, 2014) would give you Diamond status through the end of March 2016.
