THEY say the house always wins. At Crown casino they have gone to great lengths to ensure the adage holds true.

Rule changes at the casino mean the house does not lose when it has a hand of 22 in Blackjack Plus - a version of the world's most popular casino card game.

Blackjack is also commonly referred to as 21 because the aim is to get 21 and not go over. But under Blackjack Plus, which is the form of blackjack on all low-bet tables at Crown, a ''stand-off'' occurs if the dealer's hand is 22, meaning no one wins.

Players are not given the same leniency if they go over 21.
