ADT: The One Number That Decides Your Casino Offers
Last reviewed: August 2026
ADT stands for Average Daily Theoretical: your total theoretical loss divided by the number of days you actually played. It is the marketing department’s favorite number, because it answers the only question they care about: what is one day of this player worth?
How ADT is calculated
Take every rated session in a trip (or a rolling window like 12 months), sum the theo, and divide by gaming days:
ADT = total theo ÷ days with rated play
Example: over a three-day trip you generate $120, $80, and $100 of theo. Your ADT is $100. A local who plays 40 days a year at $50 of theo per visit has an ADT of $50, even though their annual theo ($2,000) is much larger than the tourist’s $300.
That distinction is the whole point. Offers built on ADT are really answering: “if we get this player here for one more day, what is it worth?”
What ADT unlocks
Exact thresholds are property secrets and vary widely, but the shape is consistent across the industry:
| ADT neighborhood | What typically shows up |
|---|---|
| Under $50 | Basic mailers, small free play offers |
| $100 to $200 | Discounted or free rooms, better free play |
| $300 to $500 | Room, food and beverage, event invites, host attention |
| $1,000+ | Full RFB treatment and a host who calls you by name |
Cruise casinos run the same logic with their own math, which is why a modest land ADT can still earn surprisingly strong offers at sea. Our cruise comps section covers those programs in detail.
The quirks worth knowing
- Days divide, so short sharp trips beat long diluted ones. Playing $300 of theo in one day produces a $300 ADT. Spreading it across three days produces $100. Same play, very different offer profile.
- A tiny session still counts as a day. Swiping your card for twenty minutes of light play on checkout day adds a divisor day and drags the average down.
- Windows roll. Most programs look back 6 to 12 months, so a big trip’s offers fade as it ages out of the window.
- ADT is not your tier. Tier points measure annual volume; ADT measures daily intensity. The mailers follow ADT.
The takeaway
You do not need to game ADT, but you should know it exists before you interpret your offers. If the casino thinks a day of you is worth $100, expect them to spend a fraction of that getting you back. Run your own numbers in the comp calculator and see whether the relationship is as generous as the mailer makes it look.
