After making your selection, you will see one of the cards displayed. Now you have to choose one of the remaining four cards. If it ranks higher than the card's ranking, you will receive double the reward. You can press the collect button to retain the new amount and exit the risk game, or continue playing the game to get a chance to further increase the bonus. You can use the "Collect" button at any time until you get an error and choose a card that ranks lower than the dealer card. In this case, you will lose the risk of the game and you will not be able to get the original return.
