Strap in to your submersible and prepare to take the plunge into a 20-payline Slot that takes place in the deepest and darkest caverns of the planet’s mighty oceans. This underwater adventure is backed with bonuses and multipliers, so your deep sea dive for sunken treasures might turn up a lot more than you expect!

Your plucky crew adorn the reels, with members of the Subtopia ship paying out anywhere from 400 to 2,000 coins for a five-of-a-kind win. This makes them the highest-scoring symbols, though even the more standard Slots card ranking symbols will be rewarding you with up to 150 coins during the regular game.

The compass scatter is one of the most valuable symbols on the reels, however, paying 100x your total bet for a five-of-a-kind win – though even a lowly pair of them will return double your bet, regardless of where they land. Hit three or more, however, and in addition to your bet win you’ll dive into the Free Spins bonus feature.

Much like the depths of the Pacific Ocean, these free spins seem to continue forever and ever. That’s because unlike most online Slots, Subtopia doesn’t give you a set number of free spins. Instead, the Free Spins feature continues indefinitely, with the prize multiplier climbing all the while!

You begin the Free Spins feature with a 2x multiplier, doubling all prizes. Keep an eye on the fifth reel during the feature, though – each time the Free Spins Multiplier Meter symbol appears, the multiplier will be cranked up to 4x and then 6x. After this, the sub can’t take anymore and the feature ends, but not after you’ve had a boatload of free spins with a 6x prize multiplier.
