Hello! The rake is the fee that a casino or poker platform takes for hosting a game. It’s usually a percentage of the pot, often between 2.5% and 5%, and serves as the operator’s main source of income. For example, a 5% rake on a €100 pot means the house takes €5 and the winner receives €95. This directly affects your profitability, especially in games with many small pots.
