Tier Points are Credits that are earned based on your casino gaming, hotel, dining and entertainment activities at over 50 Caesars Rewards destinations. Now, Tier Credits can also be earned with Caesars Sportsbook apps and most Caesars Sportsbook retail locations. You can also earn tier credit through promotions. The Tier Credits you earn in a calendar year (January 1 through December 31) add up to your annual Tier Score, which determines your Tier Status within Caesars Rewards.
