The HeavyMetal. is a three-wheel, four-payline slot machine game. Each payline which has a bet placed on it can win. Winnings are based on the symbols on each payline and the amount bet on that line. You can see symbols' combinations from your last three spins at all times. It creates three new paylines which pay off the same way as the slot's main one. If you get, say, a star on the first wheel three times in a row, you will be paid 80 times a bet on "Line A". Each wheel's history pays off in the same way, so watch the blue display to decide whether to place your bets or not. Furthermore, a feature "Hold" appears randomly during play. It lets you hold some of the slot's wheels, allowing you to determine your game history for your next spin and, occasionally, to win for sure!.
