A "gamble feature" is a function found in many online slots. It makes it possible for players to double or multiply their winnings by playing a game of luck. To activate the gamble function, you'll have to click on a button after you've gained a win. You'll then be challenged to select either a color or a card (like from a deck of poker cards). Should you make the correct choice, then your winnings are either doubled or multiplied accordingly. But if your selection is incorrect, you'll lose the winnings you just gained. Although the gamble feature can be very exciting, it is important that you denote that it is merely and entirely a matter of luck and there is no guarantee for more winnings. Thus, we recommend that you be careful with this function and only risk your winnings that you're willing to lose.
