What is the difference between theo and actual win/loss in casino gambling?
Theo (short for theoretical) is the amount a casino statistically expects to win from a player based on bet size, game odds, and time played, while actual win/loss reflects what really happened at the table. Casinos rely on theo rather than actual results to award comps because it smooths out short-term luck and reflects long-run expected value.
How do casinos calculate a player's theo?
Theo is typically calculated by multiplying average bet size by the number of hands or spins played per hour, the house edge of the game, and the total hours played. The resulting figure estimates how much the casino expects to earn from that player over time.
Why do casinos use theo instead of actual losses to decide comps and rewards?
Actual results on any single visit can swing wildly due to luck, so relying on them would make rewards inconsistent. Theo gives a steadier, statistically grounded estimate of a player's long-term value, which casinos use to decide free rooms, meals, and other perks.
