The risk game is available after any winning combination falls out in the main mode of the slot. To participate, you need to agree and try to guess the color of the face-down card and get a double win, or try to guess the suit of the card and the win will be quadrupled. Slot games work on a mechanism known as a random number generator – or RNG for short. RNG means each spin of the reels is independent from the last, and the outcome is random.
