Reef Run is a 5-reel, 20-payline video slot game that plays from left to right. It features six standard symbols that yield a win when three or more are lined up in sequence on a payline, starting from the leftmost position. The game also includes freespin symbols; three of these award 10 freespins, four award 20 freespins, and five award 60 freespins. In a Free Spin round, the Level Multiplier will increase the winnings of a symbol that is hit multiple times — the first win is multiplied by x1, the second by x5, the third by x10, and the fourth and any subsequent wins by x20. If a symbol wins twice in one spin, the same multiplier is applied to both wins.
