Theoretical Win
Definition
The amount a casino expects to win from a player or a machine, calculated from amount wagered multiplied by the house edge. The basis of player rating and comp entitlement.
Key takeaways
- Theoretical win is average bet multiplied by decisions per hour, hours played and house edge.
- It measures expected revenue from a player or machine, not what was actually won.
- Comps, tier status and host attention are awarded against theo, not against a player’s losses.
- Average daily theoretical is the standard ranking measure for high-value players.
Why it matters
Theoretical win, universally shortened to theo, converts activity into expected revenue. The calculation is average bet multiplied by decisions per hour multiplied by hours played multiplied by house edge. A player averaging 100 a hand over 60 hands an hour for four hours on a game with a 1% edge generates a theo of 240, using round illustrative figures. Actual win in that session could be anything; theo is the expectation, and it is the number the business plans on.
It matters because it is the currency of player management. Comps, room offers, host attention and tier status are awarded against theo rather than against losses, which is why a disciplined low-edge player who bets large can out-earn rewards over someone who lost more money on a smaller stake. The same arithmetic drives floor decisions: average daily theoretical is used to rank players, and machine-level theo guides which titles keep their position. Online, the equivalent measure is expected gross gaming revenue per player, and the logic of rewarding expected rather than realised losses carries across, which is also why responsible-gambling frameworks scrutinise incentive schemes built on it.
Frequently asked questions
How is theoretical win calculated?
Average bet multiplied by decisions per hour, multiplied by hours played, multiplied by the game’s house edge. The result is expected revenue, not actual result.
Why do comps follow theo rather than losses?
Because theo measures the expected long-run value of the play. Rewarding realised losses would pay most to the unluckiest customers rather than the most valuable ones.
What is ADT?
Average daily theoretical: theoretical win averaged per day of play, used to rank players and set comp and host entitlements.
