Expected Value (EV)
A statistical term that represents the predicted average return of a wager in the long run.
Expected Value (EV) is a core concept in gambling theory used to determine the long-term profitability of a specific bet or strategy. A positive EV (+EV) indicates a profitable decision in the long run, while a negative EV (-EV) indicates a losing one.
All licensed casino games, by design, have a negative EV for the player; this is another way of expressing the House Edge. However, the concept of EV becomes crucial when analyzing bonuses. A player can calculate the EV of a bonus by factoring in the bonus amount, the Wagering Requirement, and the RTP of the game they play. A bonus can have a +EV if the terms are sufficiently generous and the game’s RTP is high enough.
