It's primarily a skill game, although luck plays a huge role. In any single given hand, luck is the predominant factor in who will win or lose. However, poker players don't play a single hand. They play hand after hand after hand & and overall, skill dominates.

Poker has a gambling element to it, which leads some players to question if poker is just down to luck. Although there is a serious amount of luck involved in poker, the fact the same big names regularly win in cash games and tournaments shows that there is skill involved.

But the most common form, and the one that PokerStars uses, is a % of the pot which is capped at a certain amount, based on the stakes being played. For example on PokerStars if you're playingR$0.01/$0.02 NLHE or PLO then the rake is 3.50% of the pot, capped atR$0.30.
