Slot— what it means in affiliate marketing
An online reel game with paylines and bonus features — the core of casino revenue.
Slots carry a published return-to-player figure, typically between 94% and 97%, and the house edge is the remainder. Everything else about them — theme, volatility, bonus mechanic — is marketing on top of that number.
