Has anyone seen this offer? https://www.caesars.com/content/dam/total-rewards/PDF/diamond_tier_upgrade_tcs_-_final.pdf It is not exactly clear how this works or if you are to gamble within each date range under item 20 or one date range. If anyone can make heads or tails out of this offer, please explain to us slow people.
You have to first be upgraded to Diamond under the tier match promotion. Then if you earn the specify amount of TCs during the one of the selected ranges, you get to keep diamond till Jan 2019 vice Jan 2018 if you were to just do the tier match. The below thread discusses a little about the tier match. https://www.vegasmessageboard.com/forums/index.php?threads/total-rewards-tier-matching.142135/
This started a little while ago. Basically, if you get your tier matched from a premium card at another property, you get upgraded to Diamond only until January 2018. However, depending on your upgrade date, you can be extended until 2019 if you earn the appropriate tier credits by 12/17, according to that chart.
