Subtopia is a 5-reel video slot equipped with 20 paylines (unfixed) and themed around underwater adventures. A coin value may be changed from one cent to $0.5, and each payline accepts up to 10 coins, so you may make a bet in the range between $0.2 and $100 with all paylines enabled. At the bottom right corner, there is a Multiplier Slider that shows your present multiplier applied to payline wins in the main game. The multiplier values are changed randomly, increasing wins by x2, x3 or x5. The first, second and third largest payouts in Subtopia are $10,000 (five Scientists or five scatters), $6000 (five Captains) and $4500 (five Librarians), without regard to multipliers.

Bonus features

A wild depicted by the Robot acts as a substitute for all normal icons and helps complete winning combinations; however, it neither forms its own combos nor multiplies payouts.

A scatter symbol (Compass) triggers a free spin feature if three or more of them land in any position. Besides, landing five scatters pays out your total bet times x100, so playing at max you can grab $10,000 on that combination. During the free spins, a Multiplier Meter symbol may randomly occur on the reels and augment your wins by x2, x4 or x6.
