The adventure at Subtopia™ begins in a 5-reel, 20-bet line main game where a random multiplier awards players with wins up to x5. In their search for the lost treasures of Subtopia™ players can also discover a Free Spins Multiplier Meter that progressively increases wins by x2 up to x6. To increase the level of excitement, players will be happy to receive an unspecified amount of Free Spins with a progressive multiplier to raise the winnings.
Base game: Wild substitutes for all symbols except scater and free spins multiplier meter symbols. In the base game a random multiplier increases betline wins by x2 to x5.
Free spins: 3 or more scatter symbols activate free spins. In free spins a multiplier meter appears at random, increasing wins by x2 up to x6. Free Spins ends when the multiplier meter reaches the crossbones.
