The Most Important Rule: Blackjack Payout

The single biggest rule variation is the blackjack payout. 3:2 pays €15 on a €10 bet. 6:5 pays only €12. That 1.39% difference in house edge makes 6:5 tables dramatically worse — avoid them entirely.

Basic Strategy Is Non-Negotiable

The house edge figures above assume perfect basic strategy. Playing by intuition instead of strategy can add 2–4% to the house edge, turning blackjack into one of the worst games in the casino. Learn the basic strategy chart before playing.
