To play the bonus card game, click on the 'Take Risk” button after winning in single spin mode. A new screen will appear with 5 cards facing down. The computer will reveal one to you, and you will then have to choose one of the four face-down cards in the hope of finding a more valuable card, which will increase your winnings.  Push the “Take Win” button to collect your money.
