Definition
Average Daily Theoretical (ADT) is the average mathematical profit a casino expects to earn from a player per day of active play. It is calculated by dividing the player’s total “Theoretical Win” by the number of unique days they gambled.
In context
If a player generates $400 in Theoretical Win on Monday and $600 on Tuesday, their total Theo is $1,000 across two “gaming days,” resulting in an ADT of $500. This $500 figure becomes the benchmark for all marketing offers sent to that player.
Why it matters
ADT is the “Gold Standard” metric for casino marketing and player reinvestment. It filters out the noise of short-term luck (wins or losses) and identifies the player’s long-term value. Casinos use ADT to segment their database into “tiers,” determining who receives free suites, airfare, or exclusive event invitations.

In detail
In the hierarchy of casino metrics, ADT is the most significant number for both the operator and the savvy player. While a player might be frustrated by a large loss, the casino’s computer systems focus exclusively on the ADT to decide the player’s future “worth.”
The Components of ADT
ADT is derived from a player’s daily “Action” and the specific house edge of the games played. Daily Theo = (Average Bet × Speed × Time) × House Edge. The ADT is then the average of these Daily Theo amounts over the player’s entire history (or a rolling window, such as the last 12 months).
ADT vs. Actual Loss
A common misunderstanding among players is that rewards are based on how much they lost. However, a player who loses $1,000 in five minutes of play has a very low ADT because their “time in seat” was minimal. Conversely, a player who loses $100 but plays for 10 hours has a much higher ADT. The casino rewards the second player more generously because they provided a greater volume of action and proved to be a more reliable source of mathematical profit.
The “Trip Killer”: ADT Dilution
The most critical error a player can make regarding their ADT is “diluting” their average. Because ADT is an average based on “gaming days,” any day where a player uses their loyalty card counts as one day.
- Scenario A: A player gambles for 5 hours on Friday with a $100 average bet. (Daily Theo: $500. ADT: $500).
- Scenario B: The same player returns Saturday morning just to use a $10 food coupon, plays for 5 minutes, and leaves. (Daily Theo: $2. New ADT: $251). In Scenario B, the player has halved their ADT in the eyes of the casino’s marketing system, which may result in a sudden drop in the quality of their future offers.
Reinvestment and Tiers
Casinos set “Reinvestment Rates” based on ADT. A typical rate might be 25%. If a player’s ADT is $400, the casino “budget” for that player is $100 per day. If the player requests a room that costs the casino $80 to provide, they are “within their numbers.” If their ADT is only $50, they will likely not qualify for free rooms. Understanding ADT allows a player to maximize their rewards by concentrating their play into fewer, higher-intensity days rather than many low-intensity visits.
