ADT stands for Average Daily Theoretical. In casino language, ADT is the casino’s estimate of a player’s average expected loss per rated gambling day. It is a short label for one of the numbers behind comps, free play, hotel offers, host attention, and mailers.

Where You See It
You see ADT in casino host conversations, player-development notes, offer planning, loyalty reports, casino marketing segmentation, and comp review. Players may hear a host say “your ADT” without seeing the exact number.
ADT is an internal player-value metric, not a public revenue category. Public revenue sources use broader metrics such as win, gross gaming revenue, hold, or gross gambling yield. The AGA Commercial Gaming Revenue Tracker tracks commercial gaming revenue, the Nevada Gaming Control Board publishes gaming revenue information, the UNLV Center for Gaming Research collects casino statistical reports, and the UK Gambling Commission explains gross gambling yield reporting.
Why It Matters
ADT matters because it can affect what the casino sends you later.
Many players focus only on today’s win or loss. The casino may focus on expected value per rated day. If you play heavily one day and lightly the next, the average may change. If you insert your card for a few casual spins on a separate day, some systems may count a low-value gaming day.
The exact rules vary by casino, but the general idea is the same: ADT turns rated play into a daily value estimate.
Example
A player generates $1,500 in theo during one rated day. The ADT is $1,500.
If the same player generates $1,500 in total theo over five rated days, the ADT is $300. The total play is the same, but the average daily value is lower. That difference can affect offers.
From the Casino Side:
From the casino side, ADT is a ranking tool. It helps marketing decide which offers make sense, helps hosts understand comp potential, and helps management control reinvestment.
A host may still use judgment. A player with a strong history, large actual loss, premium hotel spend, or strategic value may receive attention beyond a simple number. But ADT is often the starting point.
Common Misunderstanding
The common misunderstanding is thinking ADT means “average daily loss.”
It does not. ADT is theoretical. It estimates expected casino value from rated play. You can win and still create ADT. You can lose and create low ADT if the rated action was small.
Hard Truth
ADT is not a sympathy number. It is a business number. The casino is usually measuring expected value, not how frustrating the trip felt.

FAQ
What does ADT stand for?
ADT stands for Average Daily Theoretical.
Is ADT the same as Average Daily Theo?
Yes. Average Daily Theo is a common spoken version of Average Daily Theoretical.
Is ADT based on actual loss?
Usually no. It is mainly based on expected loss from rated play.
Why do casino offers change after small visits?
Because a small rated visit may count as a low-value gaming day in some systems, lowering the daily average.
Should players chase higher ADT?
No. Chasing offers by gambling more can be expensive. If this term describes pressure you feel, the smart move is a pause, not a bigger bet.
Deeper Insight
ADT exists because casino databases need a simple way to compare players who visit differently. One player may play hard for one day. Another may spread the same action across a week. ADT makes those patterns comparable, but it can also create surprises when casual low-play days count.
Formula / Calculation
| Metric | Formula | Plain-English meaning |
|---|---|---|
| ADT | Total theoretical loss / Rated gaming days | Expected value per rated day |
| Table theo | Average bet × Decisions per hour × Hours played × House edge | Expected casino win from table play |
| Slot theo | Coin-in × Slot hold percentage | Expected casino win from slot play |
| Offer value estimate | ADT × Reinvestment rate | Rough value the casino may return |
Formula Explanation in Plain English
If your total theo is $800 over two rated days, your ADT is $400. If the same $800 is spread over four rated days, your ADT is $200. The casino may see the second pattern as lower daily value even though the total theo is identical.
