If you are playing a standard Blackjack game variant, then the very highest paying hand you can be dealt out is a Blackjack hand that being any Ace and any 10-valued playing card that has been unmatched by the Dealers hand. Some land based casinos offer you a winning payout of 3 to 2 for such a hand however other casino may pay you a much smaller valued winning payout for those hands that being 6 to 5 so always make sure the variant you are playing offers a 3 to 2 payout and not a 6 to 5 winning payout!
