Cashback is a general term used across many casinos, including Kirpee Casino, to describe a mechanic where a portion of play is returned to the player rather than kept entirely by the house. It is a different idea from a deposit bonus, because it relates to how you have already played rather than to money you are about to add.
The word itself simply describes the direction the money moves: back toward the player, cash rather than free spins or credit. Beyond that shared idea, the specifics, such as how often it is calculated or in what form it arrives, are set individually by each casino, and they can differ quite a lot from one operator to another.
At Kirpee Kasino, the headline figure is 20%. What that percentage is calculated against, and how often, is shown inside the casino itself, where the current and exact version of the offer always lives, kept up to date as the terms are refined.
