Hi-Lo Premium

Make profitable predictionsin this exciting guessing game!

The main objective of playing Hi-Lo Premium is to place bets on whether the next card to be revealed will be higher or lower than the last. This premium version of a casino classic will allow you to bet on several further options, including suit colour, card ranges and specific cards. This easy-to-play casino game is sure to be a big hit among fans of online blackjack, poker and other card games.

How to Play:

The game is played with the following card selections:


2, 6 and Jack


3, 7 and Queen


4, 8 and King


5, 9 and Ace

The cards are arrayed in order (2 the leftmost, Ace the rightmost) face down on the top of the screen. One card will be revealed, with the odds of the Higher/Lower betting selections displayed to reflect probability.

  • Use the Stake Up/Stake Down buttons to adjust the initial bet for the round.
  • Click on one of the following betting options to start the game:

Bet Type:

Betting on:


The next card will be higher than the last.


The next card will be lower than the last.


The next card will be the same as the last.


The next card will be an Ace.


The next card will be an Ace or King.


The next card will be red.


The next card will be black.


The next card will be Ace, King, Queen or Jack.


The next card will be from 2-9 inclusive.

Once you have made your selections, the cards will start flipping in order on the top of the screen. Eventually, the flipping will slow and stop on the winning card.

If your prediction is a winning one, you will be offered the chance to Save Some (bank some of your winnings and continue playing with the remainder) or Take All (bank all your winnings).

Please note:

  • All odds for Higher and Lower are based on probability. For example, betting Lower on an Ace would have lower odds than betting Lower on a 7. All odds are displayed beside each betting option.

Bet X 11.7


Bet X 11.7


Bet X 5.85


Bet X 1.95


Bet X 1.95
