Average Daily Theoretical, often shortened to ADT or Average Daily Theo, is a casino’s estimate of a player’s average expected loss per rated gambling day. It is one of the most important numbers behind casino offers, comps, free play, rooms, and host attention.
Plain Talk
ADT is not what you actually lost. It is what the casino expected to earn from your play on an average rated day.
If you play one strong day and two tiny card-in days, your average can drop. If you play steady action across several days, your average may look stronger. That is why experienced players pay attention to rated days, not just total loss.
| Term | Plain-English meaning | Where it appears | Why it matters |
|---|---|---|---|
| Average Daily Theoretical | Expected casino win per rated day | Offer engines, host systems, comp reviews | Drives many casino offers |
| ADT | Short form of Average Daily Theoretical | Player-development language | Same concept, shorter label |
| Theo | Expected casino win from play | Ratings, comp systems | Raw value before averaging |
| Rated day | A day with recorded player-card play | Loyalty systems | Changes the average |

Where You See It
You see Average Daily Theoretical in casino loyalty databases, player-development reports, host reviews, comp calculations, mailer decisions, free play targeting, tier analysis, and promotional segmentation. Players usually do not see the exact internal number, but they feel its effect through offers.
Public casino reports normally discuss market-level win, revenue, and hold rather than individual ADT. The AGA Commercial Gaming Revenue Tracker reports broad commercial revenue categories. The Nevada Gaming Control Board publishes gaming revenue information. For research summaries on gaming win and related metrics, see the UNLV Center for Gaming Research. For formal UK reporting language around gambling yield, see the UK Gambling Commission GGY guidance.
Why It Matters
Average Daily Theoretical matters because many casinos build offers around expected value, not emotion.
A player may think, “I lost $1,500, so I should get a big offer.” The casino may think, “Your rated play created $300 in theo over two gaming days, so the offer must fit that value.” Those are different conversations.
ADT also punishes casual card use in some systems. If a player cards in for five minutes on an extra day, that day may count as a low-value rated day. Depending on the property’s rules, the average can drop.
Example
A slot player produces $1,200 in total theoretical loss during a trip.
If all of that play happened on one rated day, the ADT is $1,200. If the player spread the same total theo over three rated days, the ADT is $400. Same total theoretical value. Different daily average. Different possible offer strength.
That is why ADT is powerful and sometimes misunderstood.
From the Casino Side:
From the casino side, Average Daily Theoretical is a database shortcut for ranking player value.
Marketing uses it to decide free play, room offers, event invitations, and mailer tiers. Hosts use it to understand whether a player supports discretionary comps. Finance uses it to compare reinvestment against expected value. Operations teams use it to avoid overreacting to a player’s lucky or unlucky trip.
ADT helps casinos scale decisions across thousands or millions of players.
Common Misunderstanding
The common misunderstanding is thinking ADT equals actual daily loss.
It does not. ADT is theoretical. A player can win money and still generate high ADT. A player can lose money and generate low ADT. The key inputs are rated action, house edge, game speed, time, and how many rated days are counted.
Hard Truth
Your casino offer may remember the five-minute card-in day better than you do. In ADT systems, small rated days can drag down a strong gambling trip.

FAQ
What does Average Daily Theoretical mean?
It means the casino’s estimate of your average expected loss per rated gambling day.
Is ADT based on actual wins and losses?
Usually no. ADT is based on theoretical value from rated play, not just what happened in the short term.
Why can one short play day hurt offers?
Because some systems count that day as a rated gaming day. If the play was tiny, it lowers the average.
Do all casinos calculate ADT the same way?
No. Systems and policies vary. Some properties count gaming days differently, use rolling periods, separate slot and table play, or apply manual host judgment.
Is higher ADT always better for the player?
It may mean stronger offers, but it also means the casino expects more gambling value from the player. Higher offers are not free money; they are tied to expected loss.
Can a player see their ADT?
Usually not directly. Some hosts may discuss value in general terms, but the exact internal number is normally not shown to players.
Deeper Insight
Average Daily Theoretical is a compression tool. It turns messy behavior into one useful marketing number. That makes it powerful, but also imperfect.
A clean ADT view requires reliable tracking. Slot tracking is usually precise because every carded spin can feed coin-in and theo. Table tracking depends on human ratings: average bet, time played, game speed, and house edge. A bad rating can distort ADT. A missed player card can erase value. A short carded visit can lower the average.
Formula / Calculation
| Metric | Formula | Plain-English meaning |
|---|---|---|
| Table theoretical loss | Average bet × Decisions per hour × Hours played × House edge | Expected casino win from table play |
| Slot theoretical loss | Coin-in × Slot hold percentage | Expected casino win from slot play |
| Average Daily Theoretical | Total theoretical loss / Number of rated gaming days | Average expected value per rated day |
| Estimated comp value | ADT × Reinvestment rate | Rough daily comp budget based on ADT |
Formula Explanation in Plain English
If you generate $900 in total theo over three rated days, your ADT is $300. If the casino reinvests 25%, that daily value might support about $75 in offer value per day, depending on property policy, market pressure, and your history.
