How to read the numbers
- Theoretical loss (theo) — what the casino expects to win from your play: average bet × decisions per hour × hours × house edge. This is the number your player's card, your rating, and your host all run on. Read the full explainer: Theoretical Loss (Theo), Explained.
- Comp value — the dollar value of what the program gives back. Slots and video poker usually earn points on coin-in (every dollar wagered, win or lose); table play is usually rated on theo and comped at the pit's reinvestment rate.
- Effective rebate — comp value ÷ theo. This is the honest exchange rate on your expected losses, and it's how you compare programs (and play types) on one axis.
- Net expected cost — theo minus comp value. The number that matters. It is positive at every realistic rate: comps reduce the cost of play — they never make it profitable.
Where the numbers come from
Game edges are the site's own figures — exact fractions where the game is exactly solvable (roulette, baccarat, craps) and solver-derived where rules matter (blackjack, Three Card Poker); see the methodology. Program base rates are illustrative, dated in the panel above, and deliberately overridable: rates vary by property, tier, and promotion, so if your host quoted you a number, enter it in the Advanced panel and trust that instead.
