Blackjack Odds and Probability

(Casinos Guides)

Information About Payout Odds

Payout odds at blackjack are calculated as follows:

• 3 to 2 - when a player has 'blackjack' and beats the casino dealer
• Evens - paid for any other win
• Original stake bet returned - in the case of a stand off (tie) with the casino dealer
• 2 to 1 - where a player has taken out insurance against the casino dealer achieving 'blackjack'
• No other odds are paid and the casino dealer always collects stake money from losing hands without insurance
